If you don't like unions, your life in this industry is really going to be limited.
1. You stay where you are the rest of your career.
2. You go to work for some No-union airline.. ummmm Jetblue is all i can think of.
Either way... you have limited your chances at advancement. Maybe your young, but even that you will outgrow.
OR....You can lose you're retirement and have to go get ANOTHER job when you hit 60! Go alpa?
