Hi I've ben working at UPS for about 6 weeks as a unloader. Now that peak season is over, my supervisor told me and a few others that they have very "low volume" from now on and told us we aren't needed anymore.I am confused because i was paying my union dues and now it looks like they will "call me whenever they need me" but i am still an employee and i thought we are guaranteed a certain amount of hours each week......
