Depending on the timing you can end up in a training event during the master bidding process so you can't bid for vacation until you are off oe and have another whole year without vacation.

I'm just ticked off that i can't use vacation that the company provides me. They know how much vacation we all get. They should be staffed with reserves to cover every one of our vacation days. What we need in a new contract (among other things) is a mechanism that allows us to use our vacation. Vacation is hugely important to the quality of life for me and my family. To be continually denied vacation month after month, year after year is something that needs fixed.
