But they do have the power to do something about it.
For a good example, I loathe the catholic church. I think they are an outdated organisation that does far more harm than good, that their views on contraception are getting people killed, that their homophobia and misogyny are archaic and disgusting and that, while they proclaim themselves as a great charitable organisation, the fast wealth they flaunt given every chance tells another story. The cover-ups for pedophiles is just the icing on the evil cake.
My first job out of university was for a Catholic school.
If my employers had been able to read my posts about the church, there is no way I would have gotten that job. I'd likely have not gotten my job at another school later on either, because their legal advisor would caution against hiring someone who may later be accused of religious discrimination.
Sure, you could pass a law prohibiting discrimination in employment or services based on personal views - but it'd be very hard to enforce.
