I'm in the same field of work as Turbo Tim 1.
Last job used to run my azz ragged. I sometimes still managed some "quality time", but only when things were quiet. Which wasnt too often. This job was rotating shifts, 12 hr shifts, sometimes a few weeks in a row. :{ Even though it's the best $$$ I ever made, I dont miss it one bit.
The job before that was another story. The shop steward so much as gave me Cart Blanche there. Even though, I still never abused it. This job was steady midnights, 8hr days, 5 days a week.
Most of the "better bosses" dont care what you do as long as everything's running good, and all things are squared away. This is the way it should be.
I now have a sleep abnia, so I can nod off at any time. :-laf
