I’ve been a driver for about a month now. There was a Tropical storm last week. I pulled my truck a little closer to the house I was delivering to because of the wind & rain. When I finished my delivery I backed up & hit a mailbox. I reported the accident immediately to my Supervisor and the homeowners. Now I am back in the building and my supervisor said I was disqualified from going back on the road. How can I be disqualified during peak season when they said we couldn’t even qualify right now? Should I file a grievance? I worked too hard to be back in the building already.
