I am only required to give 30 days' advance notice of retirement, but I have been with my employer for a long time, I have generally been treated very well, and the employer would certainly benefit from having more notice. So I am thinking that I would give about 6 months' notice. I have no concern they would terminate me when I give the notice (they would never do that, and on the one-in-a-million chance that I'm wrong about that, I would not care). Other than that, what might I not be thinking of? Are there reasons why I should not give, say,, 6 months' notice? I can't think of any, but maybe there's something I'm not thinking of?
