At the tactical level, your union rep is just the shop steward on the floor, so another MCpl or Cpl who represents your interests. It is only once something goes above a Level 3 grievance does anyone senior get involved. I have been the Level 5 Grievance decision maker before, and adjudicated and heard complaints. The members were either represented by a coworker who was their stewart, or in one instance when no on would represent the guy, the local president. The same perceived blowback on the shop steward and the member would happen in our current system, and have more career impacts for military members than it does now for PS, because their advancement is still in the hands of their supervisors.
