If you're hired at the wrong time, you'll be on 7th year pay before you actually get your 3rd week of vacation. Woohoo! Vacations are bid in blocks of 7 and ONLY blocks of 7. If you're out for any reason during there year you may get docked days, which means you no longer can bid that week as a separate vacation block. For example, if you're docked 1 day of vacation, they simply tag the remaining 6 day onto your first week of vacation. The catch is, BOTH weeks have to be available...seems legit!

If you happen to be in a leave status during vacation bidding, you'll get what's lefter over and like it! Best you can hope for is a move-up.
Our vacation needs a lot of work!
