I'm not sure I'd change anything.
One thing I do wonder about is, twice over the last 35 years I left jobs because of impossible conditions. In both cases conditions were clearly made impossible so I WOULD leave.
I worked my tail off until I clocked out the last day, and left quietly.
I wonder if I should have given my bosses a piece of my mind and left in a huff.
Not sure that would have been a good idea however. As my dad would say, your reputation is very important. Because of how I conducted myself, I was unemployed a total of 2 days, the first time, and 4 days the second.
And, in the "there is a God" department, in both cases my departure caused huge problems for the bosses who wanted me out, and in the last case, cost the company over $20,000.
