Hello I have a slight issue due to the fact that my seniority was sort of taken away. I am a combo worker 22.3, working 5 hours in the warehouse and 3 hours delivering air. Usually in my area of the warehouse we are sometimes overstaffed and they ask workers if they would like to go home starting from highest seniority to lowest. I have been in the same area of the warehouse for 17years even after I got the combo job 5 years into UPS. Well since I am third in seniority they ask me if I want to go home usually I say no but sometimes I am beat and decide to leave and get a couple of hours shut eye before heading to my second shift. Well it seems a part time worker who is also a union representative had an issue with that. She decided to go to the union and she established that they are not suppose to ask me if I can go home but rather ask all the part timers first and if they don't want to go home then they can ask me. Her reason was that since I am full time, my hours are guaranteed and should not be allowed to leave until the part timers leave first. This seemed kind of strange to me because they would ask me by my seniority for about 12 years and all of a sudden she takes that away from me. I am not looking to go home everyday but I do want to be asked if I would like to go home just as an option, can anyone tell me if she has a case to get away with this.
