The authors contend that turning the spotlights from state to workplace accommodation of Muslim’s religious practices allows discovering different answers to the how’s and the why’s of minority religious accommodation. Different than state accommodation of Muslim’s religious practices, which are often formally regulated and accompanied by an external and polarized public debate with opposing ideological argumentations, this article will show that workplace accommodation of Muslim’s religious practices presents different features. The empirical analysis demonstrates that workplace religious accommodation is characterized by 3 ‘i’s: it is granted or refused on the basis of instrumental argumentations, it is regulated informally and resolved internally. The article explains these specific features of workplace religious accommodation of Muslim religious practices by their fit with post-fordist features of the employment sphere in general, and by the neo-corporatist employment relations for Belgium in particular.
