I'm sure this week is a nightmare for FAs across Canada, with the vaccine requirement being lifted, but the mask mandate still in place. A lot more talk about "my rights" and "freedom" than there has been.
Personally, I say you get one warning, then they should boot your ... off, and hand you a 5 year ban to go with it. These are the rules of flying at the moment, so comply, or stay at home. Air travel isn't anywhere near a guaranteed right.
The airport/airplane is pretty much the only place I'm wearing a mask any longer, but I do so without outward complaint. I think it's dumb, but it's the rules I agreed to.
