Racer is right. Bad employment history can really count against you. Try to stick it out, even if the company does "suck" for at least six months. That will allow you to get into a groove. If it still sucks after that, maybe try to talk to someone in your company (trainer, dispatcher) and try to hash it out. Maybe things could be worked out through good communication. If not, then you can try another carrier. That way you can tell your next employer that you tried to make things work but maybe that company just wasn't the right fit for you.
