On our shift the sups, who are still pretty new, are kicking people, I being one of them, off the sorting jobs. One of the newbie sups said it was for performance but none of us have been disciplined for missloads or anything else. Not even verbally. So we have been kicked off for no reason and newer guys with less seniority are making more money. The newer people have been getting missloads but haven't been moved yet so what gives? Can those of us that have been moved, and have more seniority, make of case of it? We don't have "bid jobs" but I think it's wrong that we are being forced out out of jobs for no reason and making less money. Can anything be done about this or is this yet another issue that falls into the cracks of the contract?
