The person I am replying to lumped all citizens of the US into a singular belief
Nope they didn’t do that. Neither did I. But maybe you should look up, what it means to be a citizen.
But, that aside, to answer your question; No, not at this time.
My question was rhetorical, and this doesn’t even answer it in the slightest.
As long as the employer has any say in, when the PTO is taken, they have a responsibility Period
In my country you have to inform your employee, when their vacation days are about to expire and make measurable efforts to find a vaccination schedule that works for both of you. Or else they don’t expire.
Or you know, you could talk to your employees and work out a schedule over the year, that works for both of you. If you, as a business, are unable to do basic management tasks, then yes you run into the situation, where you are functionally unable to do business at the end of the year.
