I got real tired of flying with first year guys who'd sit down next to me, and would complain about pretty much everything: Pay, workrules and as soon as they get their 1000 PIC, they're in indoc at FDX/WN/UPS.
Not every FO is this way, mind you, but there was a definite trend. Looking in the rear-view, it was worse than I'd observed.
Your first year you're on probation. If you hit the books right, learn your GOM(FOM), SOP(POH) and learn how to fly the plane, you prolly won't have to be scared at recurrent time.
