If contract doesn't state how long one needs to stay, it is professional to leave anytime. I had the luck to get into a company which was (to some extent is) a mess, where I had (have) so many opportunities to improve things and get paid for it. Noone told me to improve things, many (including my bosses) told me not to poke around. I stopped asking, did it anyway, presented measurable improvements, got raises and respect from some, hatred and envy from some others. Latter ones usually got sacked in the long run, so I guess not everything is a mess, someone up there cares. I don't think I owe company anything, or company owes me. I do stuff, I get paid. What I think I do owe is real-time feedback about state of stuff under my care, about my long-term goals and money expectations. Company owes me timely paycheck for time and money we agree upon. Debt from both sides is erased monthly, on payday. I left some companies. I stayed at some. All's fair in love and war.
