A summary of the ruling is here: AP: The Supreme Court bolsters protections for workers who ask for religious accommodations

Here’s the takeaway: We shouldn’t be relying on Hardison’s “de minimis” language to deny requests for religious accommodations that would have a relatively minor impact on operations. Rather, we should look at whether granting a proposed religious accommodation would impose “substantial additional costs” on the employer’s business. Said differently, for religious accommodations, we shouldn’t be denying proposed accommodations if they would only have a very minimal impact/cost on operations.
