First, there is a difference between employing somebody and a violation of their religion. It isn't against their religion to give a person a job, even if they are a sinner. Hiring a gay person isn't against their religion, it isn't immoral to do such a thing, giving them an abortive agent or providing birth control for another is an action that is a sin according to their religion, it is immoral and the Free Exercise of their religion guaranteed in the 1st requires government to allow them to make that decision.
If they want birth control they need to get it from a different source than the church. It isn't even unreasonable, it is affordable, and they chose to work for an employer they knew would not provide such things.
Who says this and that is against their religion and this and that is not?
Have you given any thought to what this would mean for women employed by Muslims or black by those who believe their pigmentation is a curse from God?
Selling crafts is not a religious function. If doing so forces you to violate your religious beliefs then maybe you should sell or close. But due process ensures that we must all be equal before the law.
