From the abstract:

With its decision in the Abercrombie case, the US Supreme Court has shown growing understanding of equality in its true, substantive form. It has taken a significant step towards protecting applicants and employees from religious discrimination and shown its progressive approach by highlighting that, in order to comply with equality law, employers may need to provide accommodation for religious practices. Despite critique on the practical side of some aspects of the ruling, the Court has made a substantial contribution to enhancing equal opportunities in the US employment market. This note will briefly discuss why the judgment has such positive implications and attempt to address some of the practical challenges the ruling may impose.
