I think you're right, but it wont stop at federal employees.I think the Feds are going to beat federal employees into submission too when it comes to getting vaccinated.
From personal experience dealing with lots of critical, vented Covid patients it almost appears as if the virus was engineered to target a very specific group, because about 90% of the patients I have cared for on vents are all from one very specific group or demographic. Possibly a coincidence, but odd to say the least.
