At a hub that isn't posting new bid jobs, air, or package car... I am seeing management wearing brown uniforms EVERY day...driving air or ROUTES in the morning after preload. It is really starting to get on my nerves, this has been going on for MONTHS now and I'M sick of it. They are using management to fill in for what they are NOT bidding. As I understand it, this is a violation of the contract...right? What can I do about it...go to the union? I've never filed any complaints and I'm wondering the pro's and con's of doing so. Thanks.
