If this were the case in question we are discussing. I would say the same thing, too bad so sad. He would have had to known he was delivering' abortifacients' if he does not like it he should have never signed a work contract or shook the owners hand and taken the job. So he nor any government agency would have any basis in suing if he lost his job for refusing literal delivery of abortifacients, IMO.
Yeah, this seems obvious to me. If your religious beliefs keep you from doing a job that employs you, then find a new job. On the other hand, if you own a business and don't want to serve people, that's up to you, and the public can boycott/picket/whatever your business. In my free market mind, the business owner makes their decisions, and the employees and public responds.
