True, no “mandate”...but they sure did press them hard over it. Perhaps could be seen as coercion. Get the shot, or you don’t start (or play) kind of hints.

He refused to get vaxxed
Interestingly, he wasn’t fired.
Imagine what we could have done, what we could have prevented if we had all displayed some guts and had stuck together.
