My hub manager wants me to write a letter of complaint towards my belt supervisor. I have no problem doing this because the guy was terrible, I guess they are trying to fire him, I dont know. But I have been reading over my contract with the union and ups and have two quick questions. 1. My supervisor has denied me a drink of water after having me work through on break. Is this allowed? 2. My supervisor has potentially lied to me how seniority works (have asked a lot of people, no one seems to know how it works so i cant call him out on his bull) He says since I have the most seniority out of the loaders, I HAVE to stay late, even though Im ranked 4th highest seniority on the belt, only one that stays late. Dont mind doing this, dont like being lied to. Thanks!
