This paper discusses the relationship between the religious practices of Muslim employees and the requirements of the workplace. It is designed to provide information on the norms of Islam and the difficulties involved in its workplace practice, and to propose suggestions for resolving these difficulties that can form the basis for discussion and implementation in particular cases. The religious requirements of Islam as well as the timing of religious practice are discussed. The authors propose that the main causes of difficulty for Muslim employees appear to be the following: (1) employers' and employees' misunderstandings of the content of Islam, (2) employers' fears that production will be jeopardized by allowing a part of the workforce to take time off to follow religious practices, (3) the absence of joint discussion and agreement on company policies regardlng the performance of religious duties, (4) fears of Muslim employees that their rights are not adequately respected, and (5) fears of non-Muslim employees that catering to the religious needs of Muslims results in favoritism. The authors suggest that employers provide facilities which would allow Muslim employees to fulfill religious requirements with as little interference with work as possible. It is also suggested that employers reach agreements to provide time off for compulsory prayer during Id Al Adha. (MK)
