No it isn’t.
Get a student aid job. Almost every college in the country requires students to be MMRed up. And hospitals generally require employees to be vaxed up, MMR, flu, you name it.
It’s not coercion. It’s following the CBA the players voted for. Their CONTRACT says the NFL can make rules and violations of those rules results in fines. Their UNION agree that the covid vax could be on the list of required behavior. NOT COERCION.
Ahh...Now that I know you are student aid. That explains everything. Haha!
Once you get out in the real world then you will have better idea how things work.
Hey when I was your age I thought I knew everything too. It’s okay to be that way.
What you are going to eventually figure out is the older the more you realize how little you know.
Have a great day.
