Okay, maybe I shouldn't admit this, but.....
I had a good long talk with my direct boss and with my general manager (each separately, one on one). I've decided to stay with conditions. If I need a bit of time off, I am to take it, no arguments, even though we're heading into the busiest time of year. My GM would rather lose me for a day or an afternoon than forever. Once the Christmas season is over and things calm down a bit (February), I'm taking four weeks off so I can regroup and come back at my usual 110%. We'll see what happens.
Meanwhile, I think I'll plan for a long weekend in New Orleans in February.
