Hello, im new to this but here i go. I've been a Ups employee for around 7 years, around 4 years ago i was given the oppurtunity to go cover driving. 3 years later i got laid off (sent back to my twilight shift). I never became a full time utility driver. When i got sent back to my twilight area the Superviser said that i had lost all of my senority. He says the new hires who started a week ago have more senority than me. Is this True? Second, This "SUPERVISER" Has done nothing but treat me with disrespect from the moment i came back. He yells obsenities, tells workers off. I am personally getting fed up with his act. i dont want to lose my job by saying something back but i keep finding it harder and harder to keep quiet. I NEED HELP. WHAT CAN I DO?
