Union bosses warn postal workers are told to prioritise parcels over letters

The Royal Mail has become 'chaotic', with post workers being told to leave doctors' and hospital letters on racks to prioritise parcels, trade union bosses have warned. The Communication Workers Union (CWU) told MPs that postal workers are led by a pyramid framework which tells them which deliveries to prioritise over others. At the top of the pyramid is special delivery items, followed by parcels or tracked items, then first-class mail, leaving second-class mail at the bottom.
