Cases 23-CA-9458 and 23-CA-9599 9 December 1985 DECISION AND ORDER BY CHAIRMAN DOTSON AND MEMBERS DENNIS AND JOHANSEN On 31 August 1984 Administrative Law Judge Leonard M. Wagman issued the attached decision. The Respondent and the General Counsel filed ex- ceptions and supporting briefs. The National Labor Relations Board has delegat- ed its authority in this proceeding to a three- member panel. The Board has considered the decision and the record in light of the exceptions and briefs and has decided to affirm the judge's rulings, findings, I and conclusions2 only to the extent consistent herewith and to adopt the recommended Order as modified. The judge found that the Respondent violated Section 8(a)(5) and (1) on 26 June 1983 by chang- ing the classification of Oscar Castillo from mix chemist to assistant chief chemist. We do not agree. 3 The Board has held that in order for a unilateral change in a term or condition of employment to constitute a violation of Section 8(a)(5), it must be a material, substantial, and significant change.4 In our opinion the change in Castillo's classification did not meet that, standard. Before the change, Castillo was classified as a mix chemist; however, his actual duties were as a physical tester in the laboratory. Even after the change in his classification, Castillo has spent most of his working time performing physical testing. Except for sporadic substitution for Chief Chemist Gonzales in Gonzales' absence, assistance to Gon- zales with a monthly report, and a slight increase in his hourly wage, none of Castillo's terms and conditions of employment have changed. Thus, we i The Respondent has excepted to some of the judge's credibility find- ings The Board's established policy is not to overrule an administrative law judge's credibility resolutions unless the clear preponderance of all the relevant evidence convinces us that they are incorrect Standard Dry Wall Products, 91 NLRB 544 (1950), enfd 188 F.2d 362 (3d Cir 1951) We have carefully examined the record and find no basis for reversing the findings 2 Because we agree with the judge that the enforcement of rule 8 against Lopez was unlawful, we find it unnecessary to pass on the judge's conclusion in fit 5 of his decision that the General Counsel has failed to show that union animus motivated the Respondent to discipline Lopez 3 We do agree with the judge that the changed classification did not render Castillo a supervisor In so concluding, however, we find it un- necessary to rely on Union 76 Auto Truck Plaza, 267 NLRB 754 (1983) 4 Weather Tee Corp., 238 NLRB 1535, 1536 (1978); Peerless Food Prod- ucts, 236 NLRB 161 (1978); Rust Craft Broadcasting of New York, 225 NLRB 327 (1976) 1031 find that in the circumstances of this case, the change in Castillo's classification does not consti- tute a material , substantial , and significant change in a term or condition , of employment and, there- fore, is not a violation of Section 8(a)(5) and (1).5 ORDER The National Labor Relations Board adopts the recommended Order of the administrative law judge as modified below and orders that the Re- spondent, Alamo Cement Company, San Antonio, Texas, its officers, agents, successors, and assigns, shall take the action set forth in the Order as modi- fied. 1. Substitute the following for paragraph 1(d). "(d) Unilaterally without notice to or consulta- tion with the Union hiring new temporary employ- ees at its Broadway operation, utilizing supervisors to operate its crusher at its Broadway operation, changing the bulk loader-weighmasters from hourly paid to salaried status, changing the manner in which overtime is paid to mechanics at its 1604 operation so that regular time is eliminated and only straight time is used, implementing an across- the-board pay increase whereby unit employees re- ceive wage increases if their wage rates were at or below the wage rates for the classiification of said employees, or otherwise changing the wage rates, hours, or other terms and conditions of employ- ment of any bargaining unit employees, without first notifying the Union and providing it with an opportunity to bargain collectively with the Re- spondent in good faith concerning such proposed changes; provided that nothing herein shall require Respondent to rescind any wage increases or pro- motions which it has previously granted to all unit employees." 2. Substitute the attached notice for that of the administrative law judge. o We also note that for some time in 1978-1979 Castillo was classified as an assistant chief chemist. Member Dennis would adopt the judge's finding of a violation, noting particularly that the change in Castillo's classification occurred in the context of numerous other unilateral changes in employee terms and con- ditions of employment APPENDIX NOTICE To EMPLOYEES POSTED BY ORDER OF THE NATIONAL LABOR RELATIONS BOARD An Agency of the United States Government The National Labor Relations Board has found that we violated the National Labor Relations Act and has ordered us to post and abide by this notice. 277 NLRB No. 108 1032 DECISIONS OF NATIONAL LABOR RELATIONS BOARD Section 7 of the Act gives employees these rights. To organize To form, join, or assist any union To bargain collectively through representa- tives of their own choice To act together for other mutual aid or pro- tection To choose not to engage in any of these protected concerted activities.

Upon a charge filed by the Union, United Cement, Lime, Gypsum and Allied Workers ]international Union and its Local ,560, AFL-CIO-CLC, in Case 23-CA-9458, on September 19, 1983, against the Alamo Cement Compa- ny (formerly known as San Antonio Portland Cement Company)," the Regional Director for Region 23 issued a complaint on October 31, 1983, alleging that the Com- pany violated Section 8(a)(5) and (1) of the National Labor Relations Act (29 U.S.C. Â§ 151 et seq.), by making unilateral changes in the wages and conditions of em- ployment of its production and maintenance employees without bargaining collectively with the Union which was the exclusive collective-bargaining representative of those employees, by refusing the Union's request to bar- gain about the unilateral changes and their effects, and by refusing to furnish the Union with information alleged to be necessary and relevant to the Union's ability to perform its duties as the employees' exclusive collective- bargaining representative. The complaint also alleged that the Company violated Section 8(a)(1) and (3) of the Act by maintaining an excessively broad prohibition against solicitations and distribution and by suspending employee Al Lopez2 for a period of 30 days because he ' The name of the Respondent appears as corrected at the hearing 2 The alleged discnminatee's full name on the record is Alfonso Lopez 1033 violated that rule or because he engaged in union activi- ty. At the hearing, without objection by the Company, I granted the General Counsel's motion to consolidate fur- ther allegations based on a charge which the Union filed January 20, 1984, in Case 23-CA-9599, with the com- plaint in Case 23-CA-9458. As amended at the hearing, the consolidated complaint included three additional alle- gations of unilateral action by the Company which alleg- edly violated Section 8(a)(5) and (1) of the Act. In its answer, as amended, the Company denied commission of all the alleged unfair labor practices. On the entire record, including my observation of the witnesses, and after due consideration of the briefs filed by the General Counsel and the Company, I make the following FINDINGS OF FACT 1. THE BUSINESS OF THE COMPANY The Company is a Texas corporation with its principal office and place of business at San Antonio, Texas, where it processes and manufactures cement. The Com- pany annually purchases and receives at its San Antonio plant products, goods, and materials valued in excess of $50,000 directly from locations outside the State of Texas. From the foregoing admitted commerce data, I find that the Company is an employer engaged in com- merce within the meaning of Section 2(2), (6), and (7) of the Act. II. THE LABOR ORGANIZATION INVOLVED The consolidated complaint alleges, the Company's an- swers admit, and I find that the Union is a labor organi- zation within the meaning of Section 2(5) of the Act. III. THE ALLEGED UNFAIR LABOR PRACTICES A. The Issues 1. Whether the Company violated Section 8(a)(5) and (1) of the Act by making unilateral changes in wages, hours, and other terms and conditions of employment without affording the Union prior notice and an opportu- nity to negotiate and bargain about those changes. 2. Whether the Company violated Section 8(a)(5) and (1) of the Act by refusing to meet and bargain collective- ly with the Union regarding the changes in wages, hours, and other terms and conditions of employment and their effects on bargaining unit employees. 3. Whether the Company by refusing to furnish the names, addresses, telephone numbers, wage classifica- tions, and seniority for employees in the certified bar- gaining unit, violated Section 8(a)(5) and (1) of the Act. 4. Whether the Company violated Section 8(a)(1) of the Act by maintaining the following prohibition: Distributing literature or articles of any kind, in- cluding circulation of petitions. (Any advertising matter or propaganda or soliciting for any organiza- tion will not be permitted.) 1034 DECISIONS OF NATIONAL LABOR RELATIONS BOARD 5. Whether the Company violated Section 8(a)(3) and (1) of the Act by suspending employee Alfonso Lopez because he violated the above-quoted no-solicitation, no- distribution rule or because he engaged in union activity. B. The Alleged Violations of Section 8(a)(5) and (1) of the Act On March 5, 1979, the Board in San Antonio Portland Cement Co., 240 NLRB 1168, 1170 (1979), found that the Company had violated Section 8(a)(5) and (1) of the Act since September 25, 1978, by refusing to bargain with the International Union component of the Union, designated as United Cement, Lime, Gypsum Workers International Union, AFL-CIO-CLC, as the certified bargaining rep- resentative of the following unit of its employees: All production and maintenance employees, includ- ing all employees in the Quarry Department, Ship- ping Department, Kiln Department, Finishing Mill Department, Slurry Mill Department, Powerhouse Department, Plant Office Department, Maintenance and Repair Department, Electrical Department, Laboratory Department, Oiler Subsection, as well as plant clerical employees, leadmen, truck drivers, and mechanics, but excluding all other employees, including office clerical employees, order clerks, guards, watchmen, and supervisors as defined in the Act, employed by [the Company ] at its San Anto- nio, Texas plant. In the same decision, the Board found that the Compa- ny had also violated Section 8(a)(5) and (1) of the Act by failing to furnish bargaining information requested by the International Union. To remedy the Company's unlawful refusal to bargain with the International Union for the employees in the certified unit, the Board in San Antonio Portland Cement Co., id., provided as follows: In order to ensure that the employees in the appro- priate unit will be accorded the services of their se- lected bargaining agent for the period provided by law, we shall construe the initial period of certifica- tion as beginning on the date [the Company] com- mences to bargain in good faith with the [Interna- tional] Union as the recognized bargaining repre- sentative in the appropriate unit. [Citations omitted.] The Board's Order was enforced in NLRB v. San Anto- nio Portland Cement Co., 611 F.2d 1148 (5th Cir. 1980), cert. denied 449 U.S. 844 (1980). On May 21, 1980, Administrative Law Judge James T. Barker issued a decision in Board Cases 23-CA-7182, et al. (JD-(SF)-155-80), in which he found, inter alia, that following the Board-held election on March 17, 1978, in the unit described above, and during 1979, the Compa- ny's predecessor made unilateral changes regarding wages and conditions of employment without bargaining collectively with the International Union, and thereby violated Section 8(a)(5) and (1) of the Act. Judge Bark- er's decision is currently under Board review. On July 15, 1983, I issued a decision in Alamo Cement Co., d/b/a San Antonio Portlant Cement Co., in Case 23- CA-8880 (JD-279- 83). In that case, I found that the Company had violated Section 8(a)(5) and (1) of the Act by unlawfully refusing to recognize and bargain with the International Union since July 27, 1981, and by making unilateral changes in wages, hours, and conditions of em- ployment of the employees represented by the Interna- tional Union in the certified unit. This decision is cur- rently under Board review. On October 27, 1983, Administrative Law Judge Rich- ard J. Linton issued a decision in Alamo Cement Co., Case 23-CA-9122, in which he found that the Company had made additional unilateral changes in the hours and conditions of employment of the bargaining unit employ- ees without notice to or consultation with the Interna- tional Union and thereby violated Section 8(a)(5) and (1) of the Act. Judge Linton's decision is also under Board review. The parties have stipulated that on or about the dates noted below, the Company engaged in the following uni- lateral conduct, which I find affected the bargaining unit employees, without prior notice to or consultation with the Union, and without having afforded it any opportuni- ty to negotiate and bargain: (a) About May 9, 1983, hired a new employee as a temporary laborer at its Broadway operations; (b) in June or July 1983, the exact date being presently unknown to the Regional Director, resumed operation of its crusher at its Broadway operations, uti- lizing Supervisors Sergio Zapata, Fred Contreras, and Sylvestre Ramirez, to operate said equipment; (c) com- mencing in July 1983, the exact date being presently un- known to the Regional Director, changed the compensa- tion of bulk loader-weighmasters from hourly pay to salary; (d) commencing in July 1983, the exact date being presently unknown to the Regional Director, at its 1604 operations, changed the manner in which overtime was paid to mechanics, whereby regular time was eliminated and only straight time was used; (e) about October 4, 1983, at its Broadway operations, used its Supervisor En- rique Zapata to operate a crane; (f) about June 26, 1983, changed the classification of Oscar Castillo, from mix chemist (doing physical testing) in the laboratory depart- ment to assistant chief chemist in the laboratory depart- ment; (g) in January 1984, granted an across-the-board pay increase whereby employees received wage increases if their wage rates were at or below the wage rate for the classification of said employees; and (h) in January 1984, established a regular schedule whereby Supervisor Enrique Zapata was to operate a crane 8 hours each week. In addition to the foregoing stipulated facts, the parties have also stipulated the following facts as alleged in paragraphs 13, 14, 15, and 17, in the amended com- plaint. They are as follows: 13. At all times material herein, and more specifi- cally since on or about July 15, 1983, the Union, by its agent Vice-President Paul H. Balhet, by corre- spondence to [the Company's] supervisor and agent William D. Hopper, protested the making of the unilateral changes and modifications as to mandato- ry and contractual terms of bargaining a described above in paragraph 11 and requested that [the Com- pany] contact the Union in order to arrange suitable times and dates for the purposes of meeting, discuss- ALAMO CEMENT CO. ing and negotiating said unilateral changes and modifications and their effects on bargaining unit employees. 14. [The Company] has not acknowledged and/or replied to the Union's request as set out above in paragraph 13. 15. By letter dated August 1, 1983, the Union, by its agent Vice-President Paul H. Balliet , requested [the Company], by its supervisor and agent William D. Hopper, to furnish the names, addresses, phone numbers, wage classification and seniority for [the unit employees] for the purpose of collective bar- gaining. 17. [The Company] has not acknowledged and/or replied to the Union's request as set out above in paragraph 15. The Company contended that it did not violate Sec- tion 8(a)(5) and (1) of the Act by unilaterally promoting Oscar Castillo to assistant chief chemist on the ground that, by such change, Castillo became a supervisor there- by excusing the Company from its bargaining obligation. The General Counsel challenged this contention urging that Castillo's position as assistant chief chemist did not render him a supervisor within the meaning of Section 2(11) of the Act. If, as the Company urges, Assistant Chief Chemist Castillo is a supervisor as defined in Sec- tion 2(11) of the Act, the Company had no duty to bar- gain with the Union about his promotion. See Gerber & Hurley, Inc., 269 NLRB 856, 858 (1984). As defined in Section 2(11) of the Act, the term "su- pervisor" denotes: [A]ny individual having authority, in the interest of the employer, to hire, transfer, suspend, lay off; recall, promote, discharge, assign, reward, or disci- pline other employees, or responsibly to direct them, or to adjust their grievances, or effectively to recommend such action, if in connection with the foregoing the exercise of such authority is not of a merely routine or clerical nature, but requires the use of independent judgment. This section is to be read in the disjunctive; possession of any one of the enumerated powers' establishes superviso- ry status. Eastern Greyhound Lines v. NLRB, 337 F.2d 84, 87 (6th Cir. 1964). The burden of establishing Castil- lo's supervisory status rested upon the Company. Com- mercial Movers, 240 NLRB 288, 290 (1979). Prior to his July 1983 promotion, Castillo was classi- fied as a mix chemist; however, his actual work was as a physical tester in the laboratory. Since his promotion, Castillo has spent most of his working time performing physical testing. As assistant chief, Castillo aids his immediate supervi- sor, Chief Chemist Willy Gonzales, in the preparation of monthly laboratory reports and acts in Gonzales' place when he is absent from the laboratory. During Gonzales' 2-week vacation in 1983, on two or three additional weekends in 1983, and during Gonzales' occasional brief absences of 1 or 2 hours' duration, Castillo has acted as chief chemist of the laboratory. During such period, the 1035 laboratory employees looked to Castillo for advice on their work and considered him to be their "boss." There was no showing that Castillo, whether acting in Gonzales' place or in his own right, has authority to hire, discharge, discipline, promote, or to recommend such personnel actions effectively. In Gonzales' absence, Castillo has directed employee Alfonso Lopez, who is a mix chemist, to run tests on cement. However, the record did not show whether Castillo issued such direc- tions using his own judgment, or whether he was acting as a conduit for Willy Gonzales. On occasion, Castillo uses his judgment when he notes deficiencies in the cement in production and directs employees to take cor- rective measures. During Gonzales' absence, Costillo re- quired employees to work overtime. Also, during Gon- zales' absence, employees have telephoned Castillo at home during the latter's off-day hours for advice on lab- oratory problems. In Gonzales' absence, Castillo regular- ly signs pay authorization sheets for the laboratory chemists. However, no employees have ever asked Cas- tillo for time off, nor was there any showing that he has authority to grant time off. - Unlike Chief Chemist Gonzales, who is salaried, Cas- tillo continues to be hourly paid as are the unit employ- ees. Castillo's hourly pay rate is $10.05. Mix chemist Al- fonso Lopez' hourly pay is $9.65 and the regular hourly pay rate for mix chemists is $9.23. Castillo has attended at least one supervisors' meeting, However, there is no showing that he regularly attended such gatherings.3 I find that the Company has not sustained its burden of proving that Castillo is a supervisor within the mean- ing of Section 2(11) of the Act. There is no showing that Castillo has authority to hire, discharge, or otherwise im- plement or effectively recommend any of the actions set out in Section 2(11) of the Act. Although Castillo has as- signed overtime to employees twice in the absence of Chief Chemist Willie Gonzales, there was no showing that Castillo had authority to do so when Gonzales was present in the laboratory. Since July 1983, when Castillo became assistant chief chemist, Gonzales has been absent from the laboratory on a 2-week vacation, two weekends, and for periods of 1 or 2 hours during the workday when he was pursuing personal business. It was during these periods of Gon- zales' absence that Castillo gave directions to laboratory personnel and otherwise acted as chief chemist. Al- though employees sought advice from Castillo and con- sidered him to be a "boss," there was no showing that Castillo was acting other than a more experienced opera- tor giving assistance to less experienced operators. Final- ly, I find from Castillo's testimony that since his promo- 3 I based my findings of fact regarding Oscar Castillo's status upon his testimony and that of Alfonso Lopez. Personnel Manager Manuel Galin- do's testimony conflicted with Castillo' s regarding the extent to which the latter performs physical testing and as to the extent of his authority when Chief Chemist Gonzales is present. I also noted that Galindo ap- peared reluctant to give a candid response to the General Counsel's ques- tions regarding Castillo's physical testing As Castillo and Lopez reflect- ed greater familiarity with the laboratory's operation than Galindo, and as they impressed me as being more candid witnesses, I have credited their testimony rather than Galindo's on this issue 1036 DECISIONS OF NATIONAL LABOR RELATIONS BOARD tion he continues to spend most of his working time as a physical tester. Therefore, he continues to perform unit work for more than half of his working time. I find therefore that Castillo is not a supervisor within the meaning of the Act and that he continues to be an em- ployee in the collective-bargaining unit . Union 76 Auto Truck Plaza, 267 NLRB 754, 755 (1983). Accordingly, I fmd no merit in the Company's defense against the alle- gation that about June 26, 1983, it unilaterally changed Oscar Castillo's classification from mix tester to assistant chief chemist in the laboratory department. The Company urges dismissal of the two allegations regarding the assignment of Supervisor Enrique Zapata as a crane operator on the ground that these assignments were not substantial, material changes in the terms and conditions of employment of bargaining unit employees. In support of this contention, the Company points to the credited testimony of Personnel Manager Emanuel Ga- lindo, that the Company has employed supervisors as crane operators "for at least 30 years." I also note that the Company and the Union have never executed any agreement covering the employment of supervisors as crane operators. I find merit in the Company's contention. For where, as here, no contractual provision prohibits such an as- signment and the record shows that supervisors have performed as crane operators previously, the assignment of Supervisor Enrique Zapata to operate a crane did not constitute a unilateral change. Tufts Bros., 235 NLRB 808, 809 (1978). Accordingly, I shall recommend dismis- sal of those portions of the amended complaint which allege that Supervisor Zapata 's assignment as a crane op- erator violated Section 8(a)(5) and (1) of the Act. In light of the prior fmdmgs and conclusions in San Antonio Portland Cement Co., 240 NLRB 1168 (1979), and those in Board Cases 23-CA-7182, et al. (JD-(SF)- 155-80), 23-CA-8880 (JD-279-83), and 23-CA-9122 (JD-(ATL)-94-83), and the stipulated facts, I find that, except for the issues regarding Supervisor Enrique Zapa- ta's assignments as a crane operator, the Company violat- ed Section 8(a)(5) and (1) of the Act by its unilateral conduct and its failure to respond to the Union's request for negotiations and bargaining as set forth above. In San Antonio Portland Cement Co., id. at. 1170-1171, the International Union had requested the unit employees names, classification, rates of pay, dates of hire, and copies of their benefit programs. The Board held that the requested information was relevant and necessary and that the Company's refusal to furnish it to the Interna- tional Union, as the recognized exclusive bargaining agent , violated Section 8(a)(5) and (1) of the Act. In light of the Board's holding, I find that the Company's refusal to furnish the Union's requested information in this case also violated Section 8(a)(5) and (1) of the Act. C. The Alleged Violation of Section 8(a)(3) and (1) of the Act Since 1978, the Company has maintained a list of 21 work rules which include rule 8 which prohibits employ- ees from: Distributing literature or articles of any kind, in- cluding circulation of petitions. (Any advertising matter or propaganda or soliciting for any organiza- tion will not be permitted.) Between August 22, 1980, and July 10, 1981, when the Union and the Company were engaged in collective-bar- gaining negotiations , the Company proposed a table of rules which included the following: 20. Solicitation for any cause during working time is prohibited. 21. Distribution of literature in working areas is prohibited. The International Union refused to discuss the Compa- ny's proposed new work rules . Instead , the International Union agreed that the Company could continue to main- tain the current work rules, which included rule 8 quoted above. In particular, I find from the testimony of Vice President Paul Balliet that the International Union specifically agreed that the Company could continue to maintain rule 8, the prohibition against distribution and solicitation. In 1981 employee Julio Perez solicited employees' sig- natures during working hours at the Company in support of a petition to decertify the International Union. When employee Alfonso Lopez became aware of Perez' activi- ty, he informed Personnel Manager Galindo, who said that he would investigate Lopez ' allegations. According to Lopez, the following day, Galindo re- ported that he had investigated the matter and Perez had denied engaging in solicitation. However, I fmd from credible testimony of Julio Perez, who appeared before me as a witness in Case 23-CA-8880, that Galindo found that Perez was engaging in solicitation. The record does not establish that Galindo learned that Perez was solicit- ing signatures during working hours on the Company's premises. Mix Chemist Alfonso Lopez has been a company em- ployee for approximately 25 years. Since 1978, the Com- pany has been aware that Lopez has been and is a union activist. During negotiations in 1980 and 1981, he was a member of the Union' s bargaining committee. On September 3, 1983, the Company suspended Lopez for 30 days on the grounds that he harassed a contrac- tor's supervisor, violated work rule 8 by soliciting em- ployee Isabel Jose Herrera on July 18, 1983, at approxi- mately 1:30 p.m. in the plant parking lot during Lopez' working hours, and that he had also violated work rule 15 by being away from his work station without excuse.4 * Herrera's testimony corroborated the Company 's version of the solic- itation Lopez ' version disagreed as to the time of the incident I credited Herrera. Lopez testified that he solicited Herrera on behalf of the Union on July 18, 1983, before 7 am, Lopez' starting time However, his responses to questions regarding where he was and what he was doing at 130 p m. that day, the time at which Herrera places the solicitation, were evasive Lopez testified that he was "probably running tests" and in response to a question about what he was doing at 1.30 p m on July 18, 1983, he an- swered in terms of his usual practice. In contrast , Herrera was responsive and appeared to be giving his best recollection with self-assurance. I therefore found Herrera to be the more reliable witness. ALAMO CEMENT CO. There was no showing that prior to Lopez' suspension, any member of the Company 's management talked to him about his union activity or threatened him with dis- cipline because of his union activity. The complaint alleges that the Company violated Sec- tion 8(a)(1) of the Act by promulgating and maintaining rule 8 , The complaint also alleges that the Company vio- lated Section 8(a)(3) and ( I) by suspending Alfonso Lopez because he violated rule 8 and because of his union activity . At the hearing , and in his posthearing brief, counsel for the General Counsel conceded that under the Board's decision in Jefferson Chemical Co., 200 NLRB 992 (1972), I am barred from finding that the pro- mulgation and maintenance of rule 8 constituted a viola- tion of Section 8 (a)(l) of the Act The Company and the General Counsel agree that under Jefferson Chemical, where as here , the promulgation of rule 8 was known or should have been known to the General Counsel through his investigation of earlier unfair labor practices , includ- ing the unfair labor practice charge which gave rise to the complaint in San Antonio Portland Cement Co., supra, the General Counsel may not thereafter challenge that conduct in a subsequent complaint . Jefferson Chemical Co., supra, id. at 994. Assuming that the earlier cases did not afford the Gen- eral Counsel the opportunity to learn of rule 8, a later case did . For in Case 23-CA--8880, both the Internation- al Union and the General Counsel became aware of the Company's existing work rules , including rule 8. Indeed, the parties have stipulated that in that proceeding, em- ployee Julio Perez testified as to the enforcement of the no-distribution aspect of rule 8. Yet, it was not until the instant proceedings that the General Counsel contended that its promulgation and maintenance were unlawful. However, I can agree only with the Company's conten- tion and the General Counsel 's concession that the au- thority of Jefferson Chemical Co., supra, precludes me from finding that the promulgation of rule 8 constituted an independent violation of Section 8(a)(1) of the Act. I also find that the 6 -month limitation contained in Section 10(b) of the Act bars a finding that the promulgation of rule 8, in 1978, 5 years before the initial charge was filed in these cases, violated the Act. Inland Shoe Mfg. Co., 211 NLRB 843 fn. 3 (1974). 1 do not agree, however, that the holding of Jefferson Chemical applies to the maintenance of rule 8 or its en- forcement within the 6-month limitation period. First, unlike the allegation barred under Jefferson Chemical, the maintenance of rule 8 is a continuing course of conduct which is occurring now, and its enforcement against Lopez in September 1983 could not have been litigated in the earlier proceedings involving the Company. Further, were I to rule as the Company urges, I would do violence to the policy involved in Section 7 of the Act. For if I permitted the Company to maintain and en- force rule 8, which I hereafter find to be invalid under Board policy, I would be granting it a license to interfere with, restrain , and coerce its employees in the exercise of the right to engage in union activity which is protected by Section 7 of the Act. Turning to rule 8, I find it to be unlawfully broad under the Board 's policies as enunciated in Stoddard- 1037 Quirk Mfg., 138 NLRB 615 (1962), and reaffirmed in Our Way, Inc., 268 NLRB 394 (1983). Under that doctrine, the Board has held that a broad no-solicitation rule ban- ning such activity during nonworking time is presump- tively invalid. Stoddard-Quirk Mfg., supra at 617. The Board has also recognized special business circumstances may permit a broad no-solicitation rule which includes nonworking time. Id. 'fn . 4, pp. 617-618. In the instant case, the Company has provided no evidence that its production and maintenance operation require the abso- lute ban on employee solicitation contained in rule 8. The Board in Stoddard-Quirk also held that a rule pro- hibiting distribution of literature by employees in non- working areas is presumptively invalid. Id. at 621. Here again the Company has not presented any evidence of special circumstances warranting this broad prohibition. Accordingly, I find that rule 8 is invalid. I find no merit in the Company's contention that the Union waived Alfonso Lopez ' Section 7 right to solicit support for the Union from other employees. For the Board has held that a union cannot effectively waive rights of employees to engage in concerted or union ac- tivity within the meaning of Section 7 of the Act. Massey-Ferguson, Inc., 246 NLRB 1100, 1101 (1979). Finally, the Company's contention that litigation of Lopez' suspension was barred under Section 10(b) of the Act is not supported by Board doctrine . For, the Board has recognized that while the promulgation of an invalid no-distribution , no-solicitation rule may be time-barred by Section 10(b) of the Act, the allegations that such rules have been enforced and maintained within the 6- month period prior to the charge are not barred by Sec- tion 10(b) of the Act. American Cast Iron Pipe Co., 234 NLRB 1126 fn. 1 (1978). I find that by maintaining rule 8, which prohibits em- ployee solicitation during nonworktime and prohibits em- ployee distribution of literature during nonworktime in nonwork areas, the Company is violating Section 8(a)(1) of the Act. Duralee Fabrics, 246 NLRB 677, 679, 680 (1979). 1 further find that by enforcing rule 8 against em- ployee Alfonso Lopez, by suspending him for 30 days, the Company violated Section 8(a)(3) and (1) of the Act. Duralee Fabrics, id. at 679.5 CONCLUSIONS OF LAW 1. Respondent Alamo Cement Company (formerly known as San Antonio Portland Cement Company) is an employer engaged in commerce within the meaning of Section 2(2), (6), and (7) of the Act. 2. The Union, United Cement, Lime, Gypsum and Allied Workers International Union and its Local 560, AFL-CIO-CLC, is a labor organization within the meaning of Section 2(5) of the Act. 8 I find it unnecessary to consider whether the Company also violated Sec 8(a)(3) and (1) of the Act by disciplining Lopez because of his union activity. However, if the Board disagrees with my finding that the en- forcement of rule 8 against Lopez was unlawful, I further find that the General Counsel has failed to show that union animus motivated the Company's conduct and would recommend dismissal of the pertinent complaint allegations 1038 DECISIONS OF NATIONAL LABOR RELATIONS BOARD 3. The following employees of Respondent constitute a unit appropriate for the purposes of collective bargaining within the meaning of Section 9(b) of the Act: All production and maintenance employees, includ- ing employees in the Quarry Department, Shipping Department, Kiln Department, Finishing Mill De- partment, Slurry Mill Department, Powerhouse De- partment, Plant Office Department, Maintenance and Repair Department, Electrical Department, Laboratory Department, Oiler Subsection, as well as plant clerical employees, leadmen, truckdrivers and mechanics, but excluding all other employees, including office clerical employees, order clerks, guards, watchmen and supervisors as defined in the Act, employed at its San Antonio, Texas plant. 4. Since September 8, 1978, United Cement, Lime, Gypsum and Allied Workers International Union, AFL- CIO-CLC has been and now is the certified and exclu- sive representative of all employees in the aforesaid ap- propriate unit for the purpose of collective bargaining with respect to rates of pay, wages, hours, and other terms and conditions of employment. 5. By unilaterally without notice to, or consultation with, the Union, hiring a new employee as a temporary laborer at its Broadway operations, resuming operation of its crusher at its Broadway operations by utilizing Su- pervisors Sergio Zapata, Fred Contreras, and Sylvestre Ramirez to operate said equipment, changing the com- pensation of bulk loader-weighmasters from hourly pay to salary, changing the manner in which overtime was paid to mechanics at its 1604 operations so that regular time was eliminated and only straight time was used, changing Oscar Castillo's classification from mix chemist (doing physical testing) in the laboratory department to assistant chief chemist in the laboratory department, and implementing an across-the-board pay increase whereby employees received wage increases if their wage rates were at or below the wage rates for the classifications of said employees, Respondent has failed and refused to bargain collectively with the Union and has engaged in and is engaging in unfair labor practices within the meaning of Section 8(a)(5) and (1) of the Act. 6. By refusing to meet with the Union for purposes of discussing and negotiating the aforesaid unilateral changes and modifications and their effects on bargaining unit employees, the Respondent has engaged in unfair labor practices within the meaning of Section 8(a)(5) and (1) of the Act. 7. By failing and refusing to furnish the Union with relevant and necessary bargaining information concern- ing employees in the above-described bargaining unit, in- cluding, but not limited to, the employees' names, ad- dresses, telephone numbers, wage classifications, and se- niority, Respondent has engaged in, and is engaging in, unfair labor practices within the meaning of Section 8(a)(5) and (1) of the Act. 8. By'maintainmg and enforcing rule 8, a no-distribu- tion and no-solicitation rule which prohibits its employ- ees from distributing or soliciting anywhere on the Com- pany's premises, the Company has engaged in and is en- gaging in unfair labor practices within the meaning of Section 8(a)(l) of the Act. 9. By suspending employee Alfonso Lopez for 30 days because he violated rule 8, Respondent has engaged in unfair labor practices within the meaning of Section 8(a)(3) and (1) of the Act. 10. The aforesaid unfair labor practices are unfair labor practices affecting commerce within the meaning of Sec- tion 2(6) and (7) of the Act. 11. Respondent has not otherwise engaged in conduct violative of the Act as alleged in the amended consoli- dated complaint. THE REMEDY Having found that Respondent has committed and is committing certain unfair labor practices, I shall recom- mend that it, be ordered to cease and desist from such conduct and to take such affirmative actions as I find necessary to remedy the effects of the unfair labor prac- tices and to effectuate the policies of the Act. Thus, I shall order that Respondent, upon the Union's request, cease utilizing its supervisors including Sergio Zapata, Fred Contreras, and Sylvestre Ramirez to operate the crusher at its Broadway operation. I shall also recom- mend that Respondent bargain with the Union upon re- quest regarding the effect of the hiring of a new employ- ee as a temporary laborer, about May 9, 1983, at Re- spondent's Broadway operations. Further, I shall order that Respondent, upon the Union's request, restore bulk loader-weighmaster classification from hourly paid to sal- aried status. I shall further recommend that upon the Union's request, Respondent restore the manner in which it paid overtime to the mechanics at its 1604 operation, by restoring the use of regular time instead of straight time . I shall also order that Respondent, at the Union's request, meet for the purpose of discussing and negotiat- ing the unilateral changes and modification as found above in this decision and the effects of such changes and modifications on the bargaining unit employees. In addition, I shall order that Respondent furnish to the Union the names, addresses, phone numbers, wage classi- fications, and seniority of the employees in the bargain- ing unit. Since it is possible that Respondent's violations of Sec- tion 8(a)(5) and (1) of the Act resulted in loss of earnings to the bargaining unit employees, they are entitled to compensation therefor, and effectuation of the policies of the Act requires it. Therefore, I will recommend that Respondent make whole any employee who lost wages as a consequence of the Respondent's unilateral conduct, to be computed as prescribed in Ogle Protection Service, 183 NLRB 682 (1970), plus interest to be determined in accordance with the policy set forth in Florida Steel Corp., 231 NLRB 651 (1977). Having found that Respondent unlawfully suspended employee Alfonso Lopez on September 3, 1983, for 30 days, I will require Respondent to make him whole for any loss of earnings and other benefits he may have suf- fered as a result of the unlawful suspension, such amount to be computed in the manner prescribed in F. W. Wool- worth Co., 90 NLRB 289 (1950), plus interest as comput- ALAMO CEMENT CO ed in Florida Steel Corp., 231 NLRB 651 (1977).6 Finally. I shall order Respondent to expunge from its records and files any reference to the 30 -day suspension imposed on Alfonso Lopez on September 3, 1983, and inform him by letter that it has been done and that his unlawful suspen- sion will not be used as a basis for future personnel action against him. On these findings of fact and conclusions of law and on the entire record, I issue the following recommend- ed' ORDER The Respondent, Alamo Cement Company, San Anto- nio, Texas, its officers , agents, successors , and assigns, shall 1.
