Keep smiling like the idiot they think you are.
Most days I think about leaving, for the same reasons as you.
The culture is just terrible. Even after 7 years I still feel like they are out to get me. The problem is the money is pretty good & I am just too tired to go through it all again with another company. Not very positive reasons to stay though I admit. I wish I knew all that when I joined.....
I promise myself to be the best I can be at work & not take it out on the mostly great Cockpit Crew I sit next to.
