As I recall from an earlier article, Illinois law allows pharmacists to refuse to fill a prescription to which they have religious/moral objections. If true, a company does not have the right to force their employees to sell such products. Otherwise, of course, they would.
I don't know, I would hope you are correct. But generally speaking, employers are free to restrict such things of their employees.
Vote with feet and dollars, I say.
Freedom of contract.
As you may have gathered from reading other replies on this thread, the governor recently issued an "emergency rule" eliminating making it illegal for a pharmacist to exercise such right of refusal.
