I'm not in Quebec and I don't know what effects religious symbols are actually having. Someone who claimed to be from Quebec described a couple examples to me that sounded pretty reasonable - things like someone from one religion being condemned and sentenced/fined by a judge wearing overt symbols of an opposing religion. Until I have concrete data either validating or discrediting the impact or actual occurrence of such scenarios, I'm inclined to at least consider them.
All examples were closely tied to religious influence on top of a substantial power imbalance and wouldn't really translate beyond that situation. I don't see it as being particularly different from trying to dictate who someone can date or engage in sexual activity. That's insane out of context - then add the context of a pre-existing boss-employee relationship.
