I know you can file a grievance if a sup is working instead of a part timer. But what about training? If a sup is training a new hire is it okay for them to be working then? I am a sorter and every time we get a new hire on the unload which seems to be every week since no one wants that job, the sup that trains them ends up unloading almost the entire truck while the new hire just watches. The sup has a pph of something like 1400-1500 so he is really fast and I am getting tired of sorting him all the time just because he is training someone. I can keep up fine with him, I just don't feel I should have to sort a sup. So is there anything I can do or do I just have to be annoyed with him?
