My employer requires flu shots for certain roles, and has for many years. Never a problem till a political party made dewormers an alternative to a vaccine.
They fired a few dozen people. Good news imo, they lost their ability to think.
It’s a mix. In this case there are no roles where a person is fully remote and would never interact with other humans in person in a business context. It’a never been a problem until recently.
I have colleagues in hospitals struggling with with similar problems. In one case, a group of medical professionals in a neonatal ICU refused covid and flu vaccines. Given the nature of the people whose care they are entrusted with, that’s unconscionable.
