Herdman, let's say you hire me as your sales assistant. I am a devout Muslim or Mormon (in extragreed's case, I can be both at the same time). My job is to mingle with clients and prospects and entertain them, almost all of which, requires me to provide them with alcohol. I am aware of this job duty while being interviewed. I don't dispute that I am able to perform it.
Three months into my employment, I tell you that I can no longer do a key function of my job, entertain the clients with alcohol present, because of my religious beliefs. At this point, you have no use for me.
Should I be allowed to be let go for not being able to fulfill the job requirements I agreed to when hired because of my religious beliefs or should you have to continue paying me part of your salary while having no other use for me?
