someone (you)
If you are activated before class, there is nothing you can do about that. However, Fed Ex is GREAT about keeping you at the top of the list and working with you based on your availability. On the flip side, all you have to do is make it to day one of class and you get your ever so valuable seniority number. If you get activated on day 2, take your seniority number with you and go play in the sand as long as you like. You will complete training at the first available slot upon your return and will retain your seniority.
Good luck!
