i have two situations going on and i keep getting misinformed by my fellow co-workers. 1. i've been asking to get a poll in the preload for a while now and my supervisors keep putting people with less seniority than me at the polls that open. i ask them why they got to go there when i've been asking and they say that they forgot and that im next in line, and then they do it again. i asked a supervisor what the union office would do if i went to them and complained and she said that they wouldn't do anything. then, another guy i work with told me that i could grieve and get paid for the money i've lost out on. right now they have me in the preload but they make me go back and forth between the preload and unload. what can i do? 2. a supervisor keeps telling me that i need a note from the doctor to use the restroom. i go 3 times in a 5-6 hour shift and one of the times is on a paid break. i dont take long and i tell them when im going to go. is this harassment? what can i do? thanks.
