I retired on a decent pension 2 1/2 years ago, and have been working 2 days a week at my old salary ever since. Like you, I could be let go any time, so have made the most of the opportunity. The
pitiful remainders after taxes extra salary has paid for a number of unexpected expenses (house, dental, medical).
As it happens, I enjoy what I'm doing (that's why they asked me back) and also like the current crop of "millennials" that I'm working with. If I didn't like either of those things, I would leave and probably never work again.
