We had a sup catch a driver sleeping on his route. The driver had been sleeping for over 1 1/2 hours. This driver has serious issues and has been suspected of using drugs while on duty. This sup continues to cover for him and told him to code 5 and show the extra lunch even though there are supposed to be no code 5's in our center. It has been over 10 days so the driver can't get in any trouble. The sup has told several about this so I think any investigation would prove such. Is this worth reporting the sup to the UPS help line.
