I’m dealing with the same question, but I work in the nonprofit sector and stock options aren’t a consideration.
For me, it’s a matter of advancing a retirement planned for June 2023 to June of this year or perhaps sooner. I was 70 on my last birthday so no one will question retirement, and if the MRD age hadn’t been increased I would already have planned to retire this year.
It’s normal in my field to give about six months of notice, because hiring is usually from a national pool of applicants who are tied to contracts. In this case, I’m pretty sure, however, that they will try to hire someone local, with no particular qualifications (I have a graduate degree in the field). The work environment has turned toxic and dangerous to me, and I’m not sure that I can survive until June, so I’m looking at February 28.
