i planned on filing a grievance on a full time sup working, i clocked him running packages in a bulk cart for 30 min. i told my shop steward but he told me not to bother since he was already gonna file and it would be pointless for me to do so. should i still try to file? or just let them deal with the shop stewards grievance? shop steward does have more seniority but i dont care about the money i just dont want the sup doing union work.
