Sorry if this has been asked already and sorry if it has. So today I did my rural amazon route and upon return was told to start a city route. As I loaded the route a city carrier came back and took the end portion. As I was delivering another city carrier met me and took some and then I finished about 40 packages. Mind you upon my return two rural carriers came back unsure if they were sent home as I was already leaving but another got back 20 minutes after I left and was sent home. My question everyone keeps telling me to grieve it both city and rural carriers but supposedly you can’t which is fine but why was I instructed to fill out separate times for doing city route does the pay change or something?
