Yes....and no
The FAA wants you to be successful and have a good career...on paper.
Let's say you are the BEST candidate on this bid. The new ATM calls yours for a release date and no surprise it's 52 weeks. They can hold you up to a year but not deny you career progression.
Well someone at a well staffed facility who barely meets the requirements is available now. Who gets selected?
It's not just sup bids either. Tons of level 5 people get into 12 tmu, supervisor, support specialist etc.
Not hating but the best plan is to bid facilities worse staffed than yours or with exceptions when those mou come out. If you get to (n90, a80, zma, zjx) during those special times you are NOT in the staffing number. When can we let a trainee go?
