(3) Within 60 days of receiving a claim pursuant to subdivision (c), the Labor Commissioner shall hold a meet-and-confer conference with the employee, the contractor, and all identified manufacturers and brand guarantors to attempt to resolve the claim. Prior to the meet-and-confer conference, the Labor Commissioner shall conduct and complete an investigation of the claim, shall make an assessment of the amount of wages, damages, penalties, expenses, and other compensation owed, and shall conduct an investigation and determine liability pursuant to subdivisions (a) and (b). At that same time, the Labor Commissioner shall also investigate and determine the proportionate liability pursuant to subdivision (b). The investigation shall include, but not be limited to, interviewing the employee and their witnesses and making an assessment of the amounts due, if any, to the employee. If an employee provides the Labor Commissioner with labels, or the equivalent thereto, from a brand guarantor or garment manufacturer, or other information that the commissioner finds credible relating to the identity of any brand guarantor or garment manufacturer for whom the employee performed garment manufacturing operations, there shall be a presumption that the brand guarantor or garment manufacturer is liable with the contractor for any amounts found to be due to the employee, as set forth in paragraph (1) of subdivision (a). An employee's claim of hours worked, and wages, damages, penalties, expenses, and other compensation due, including the claim of liability of a brand guarantor or garment manufacturer upon provision by the employee of labels or other credible information about work performed for any person, shall be presumed valid and shall be the Labor Commissioner's assessment, unless the brand guarantor, garment manufacturer, or contractor provides specific, compelling, and reliable written evidence to the contrary. That evidence from the brand guarantor, garment manufacturer, or contractor shall include accurate, complete, and contemporaneous records pursuant to Sections 226, 1174, and 2673, and the industrial commission wage order, including, but not limited to, itemized wage deduction statements, bona fide complete and accurate payroll records, evidence of the precise hours worked by the employee for each pay period during the period of the claim, and evidence, including a purchase order or invoice identifying the person or persons for whom garment manufacturing operations were performed. In the absence of the provision of that evidence, or the failure to timely respond to a subpoena pursuant to paragraph (1), a written declaration from a brand guarantor, garment manufacturer, or contractor is not sufficient to rebut the presumption of validity of the worker's claim and liability of the respective parties. If the Labor Commissioner finds falsification by the garment manufacturer or contractor of payroll records submitted for any pay period of the claim, any other payroll records submitted by the garment manufacturer or contractor shall be presumed false and disregarded. The Labor Commissioner shall present their assessment of the amount of wages, and each contractor's or each garment manufacturer's proportionate shares of damages and penalties, owed to the parties at the meet-and-confer conference and shall make a demand for payment of the amount of the assessment. If no resolution is reached, the Labor Commissioner shall, at the meet-and-confer conference, set the matter for hearing pursuant to paragraph (4).
