I haven't yet enlisted but I am seriously thinking about enlisting in the Marine Corps Reserves soon and going to boot camp next summer. How does that work with UPS? I know they can't legally fire me for it but will I just leave and then return into the same position? Who will fill my spot? Will it affect my benefits at all? What if I decide to just go active duty for 2 years, will they still hold the job for me? I don't want to ask anyone at my work yet. If they know I might be leaving come next summer they might just try and can my now and replace me so they don't have to worry about it later.
