I'll vouch for grievances being dumped. I had a grievance that in my opinion was 100% valid It was regarding uniform allotment on the West side. Our CBA states that on 1 January of each year we would recieve our allotment. We didn't. No new uniforms or allotments were provided until September, and the new uniforms were not permitted until October 13th. I recieved a letter from NG shortly before he left stating that the Company denied my grievance and the Union felt it would not win at arbitration, so it was dropped.
