Dont burn bridges though. If someone has acted like a dumbass at one company, everyone knows about it when they step through the door at the next. Treat every pilot you meet with respect because you will come across the same ugly mugs again and again throughout your whole career. If you make a bad name for yourself people remember.
Excellent advice
Hamley, there are operators who will ask their current pilots for a run down on the reputation of an applicant, it's not unknown for an applicant to turn up with a glowing reference from their previous employer, reason being the previous employer wants to get rid of the employee no matter what.
