It could be quite bad for morale to keep their business. You'll probably have a group that quit, plus the ones that are left but still would be unsettled by you

It could be quite bad for morale to keep their business. You'll probably have a group that quit, plus the ones that are left but still would be unsettled by you valuing a bit of $ over principles. That said, I don't think the Supreme Court ruling covers your case (you don't have a religious objection), so you might want to get council.
