Ive been with UPS in illinois for about 8 months as a part time night sort worker. I went into training to be a seasonal driver through the summer months and the sunday before i was supposed to start my appendix blew up and i had to take 8 weeks off work. Ive been back for roughly 2 weeks now and I blew my knee out in a non work related injury that may require another surgery. Im worried that my job will not be secure in this situation as I will more than likely need to be taking another 3 months off due to this injury. I currently pay union dues and my hub is pretty relaxed and no one gets fired for anything but what do you guys think? Is there any actions i should take to ensure my job will still be there when i get back?
