I've never filed a grievance before. It's my understanding that if you request to stay and management sends you home regardless you are guaranteed 3.5 hours of pay. I'm on the local sort, worked maybe 2.5 hours tonight. The part time supervisor told me to clock out because we were finished. I told him I'd like to stay, he said no there isn't anything left and to go home. Is something I can file a grievance for? The facility I'm at is incredibly small, with on average 20 routes.
