PT sup recently has been instructing a clerk (who does the re-wrapping of open packages and looks up residential addresses for correction purposes) to help DCAP at the end of the day in order to get the shift done sooner. The clerk is in a union, but not our bargaining union. She has no vote in the bargaining agreement but yet says she has to do what preload sup instructs her to do. I want to file but not sure what article and section this would fall under. Don't think I can turn in a grievance w/o an article and section numbers on it.
