When the company takes your days off away, then continues to junior man you to work on your remaining few days off, takes away your vacation, and doesn't give you your schedule until 5 days out or less of the new bid period. When you realize you'll be home just long enough to go to the bathroom, pay your bills, and wash your shirts. When maintenance tells you "Effed if I know" when you call to tell them about big ticket maintenance items and are looking for guidance on what to do next. When you bust a walnut to get to work on time, then they cancel turns so your new report isn't until 6 hours later and they deny you per diem. When you realize your company is worse than Mesa.
Then, that feeling dies.
Not that I'm bitter or anything.
