I work for a major IT company as a field service engineer and am 55 and in the same boat as you. I have to be jabbed by December 8th since I support a Federal account. I was also told that I have to comply with customer guidelines whom I service and one of the major accounts I go to has already mandated that everyone who comes onsite must be able to attest to being vaccinated so my deadline may come sooner. I have 24 years in the company and I am planning to let them fire me and take enough from my 401K to pay off my major debts take the tax hit and then maybe work in a more menial job (if there are any such jobs) or go a different direction until I can retire.
Not the way I wanted to go out but it's doable. If I can delay drawing from my own 401k for a few years, we should be home free. Good luck!
