I had a job afew years ago like this, managing a team of 5. It was 9-5, but there was just way too much to be done, so I was often there until 6, 7 and even 8:30. The office head would often pop in on his way home and ask why I was still there. I've always been the kind of person to not leave until all the work is done, but there were times I'd have to get home, so I'd just do more work at night. And on weekends. And the team members took advantage of my constant availability but would lose it if I made a mistake - which was inevitable considering the workload. I still kick myself for allowing it to happen, because I worked myself to a near-breakdown. And for what? I wasn't respected, nor was I compensated for the extra time because I was salaried. Never again.
