I would like some advice on whether to pursue a grievance, or if I should just let this situation slide. I have been with UPS part time for 6 years, spent all 6 years on the sort aisle. For several years, a particular manager has seemed to have it out for me. He has publicly taunted me and tried to humiliate me in front of my peers on several occasions. I have always just ignored it because I typically do not like to rock the boat or bring unwanted attention to myself. Other employees have consistently pointed out that this manager has it out for me. This past December, he was taunting me while I was attempting to sort and I finally confronted him and asked him why he has been harassing me. We ended up in his office with my Union representation present and he stated he would from now on, keep it 100% professional with me. Since then, he has made no further comments to me. However, today I was informed that per him, I was to be moved to small sort, even though I have never been written up for a performance related issue, and I have more seniority than 90% of the rest of the sort aisle. I was given no reason for the move other than this is what he wanted. The move would not bother me because the workload is easier, but that section gets out later and it will interfere with my full time job. Is it worth pursuing or should I just suck it up and deal with the move?
