Because theirs alternatives to taking the vaccine, like exercise and a good diet. Why isn't there and exercise mandate or a diet mandate? It sounds stupid maybe to you, but to me if they are allowed to mandate vaccines, they should be allowed to say 'your diet isn't the best and you're likely to get sick and die. You can't work here unless you exercise' which honestly is more reasonable to me than mandating a vaccine. The CDC has guidelines for health and exercise, why isn't that being pushed as hard as mask? We know your diet has a bigger impact on covid than a mask, which to properly use you need to do a test BTW. I've worked with N-95 mask before corona and not everyone can wear them. We literally had to taking a breathing test, that was very weird to do in all honesty. People failed it often.
