I am just curious about this. So I load trailers and have been for 2 years and now the building seems to be shorted staffed and they always want someone to go to unload. The belt I am on is already short on people too. My question is can I refuse to go to unload because my job is a feeder loader? Does article 22.4 (preferred jobs) section mean that I don't have to go to unload since my job title is feeder loader? I am interested on knowing more about what we actually have to put up with. Wish I could find my union book.
