Reasonable accommodation without undue hardship is generally possible where a voluntary substitute with substantially similar qualifications is available. One means of substitution is the voluntary swap. In a number of cases, the securing of a substitute has been left entirely up to the individual seeking the accommodation. The Commission believes that the obligation to accommodate requires that employers and labor organizations facilitate the securing of a voluntary substitute with substantially similar qualifications. Some means of doing this which employers and labor organizations should consider are: to publicize policies regarding accommodation and voluntary substitution; to promote an atmosphere in which such substitutions are favorably regarded; to provide a central file, bulletin board or other means for matching voluntary substitutes with positions for which substitutes are needed.
One means of providing reasonable accommodation for the religious practices of employees or prospective employees which employers and labor organizations should consider is the creation of a flexible work schedule for individuals requesting accommodation.
The following list is an example of areas in which flexibility might be introduced: flexible arrival and departure times; floating or optional holidays; flexible work breaks; use of lunch time in exchange for early departure; staggered work hours; and permitting an employee to make up time lost due to the observance of religious practices.
When an employee cannot be accommodated either as to his or her entire job or an assignment within the job, employers and labor organizations should consider whether or not it is possible to change the job assignment or give the employee a lateral transfer.
Some collective bargaining agreements include a provision that each employee must join the labor organization or pay the labor organization a sum equivalent to dues. When an employee's religious practices to not permit compliance with such a provision, the labor organization should accommodate the employee by not requiring the employee to join the organization and by permitting him or her to donate a sum equivalent to dues to a charitable organization.
