The Supreme Court decided long ago that total mandates are constitutional. These are not even real mandates: They just say you can't work here if you are not vaccinated. You are perfectly free to go do something else. Since being unvaccinated does actually present danger to the immune-compromised, the elderly, and such, there is a rational basis for these job requirements. Certain jobs have job requirements. That's all these are.
The armed forces have been very strict about vaccine mandates for a very long time. They don't even ask! They just tell you to stand in this line and get a bunch of shots.
