re: How long to give a job you hate?

You should come to grips with the reality that no job is perfect.

Every job will have at least a couple of jerks and the work will become monotonous at times, even if you like what you do. I think if the compensation is good and there are people you like there you're way ahead of the curve.

If you "hate what you do" that sounds like a much bigger problem, as in you need to go back to college.
