I recently was promoted at my current job and put on a salary. The expectation is that I put in at least fifty hours a week (ten hours per day, five days per week). I have asked this question on other sites and those who respond tend to get hung up on the fact that salaries work in such a way that it's more about completing what is expected of you than like working an exact set number of hours. That is irrelevant in the kind of work that I do, just wanted to get it out of the way before I pose my question. And besides, there is a weird culture at my office where if you finish everything you were working on ten to fifteen minutes before your day is technically over, it's apparently weird to not just sit there and wait until 5:30.
Anyway...I have decided to move back home when my lease is up, for a variety of reasons that I don't want to go into. Fortunately, his house is about an hour away from where I work, and I am able to commute to work and continue my job. However, the fifty hours per week plus ten hours of commuting puts me at a breaking point. How do I talk to my boss about reducing my work hours to 45-40 per week, with the understanding and acknowledgement that I can take a pay cut if necessary, without jeopardizing his trust and confidence in me?
