BTW. It may be worth a meeting with the principle of your current job to discuss pay and quality of life.
I agree.
Best case: You get more pay and stay.
Worst case: He rejects your proposal and you leave for the airlines, which you planned on doing anyway.
I am a believer of openly communicating things. Chances are your owner wasn't aware of your dilemma and things work out for the better. If not, you at least gave it a shot. Should be worth it, seeing as you don't exactly seem to hate it there.
