Had two separate but similar instances with our on-road supes where other drivers gave me a heads up they were doing hourly work. Used my network to gather as much info as possible and had a good idea what went down before I confronted them on it. Never let them know what you know. I kept questioning them, catching them in lie after lie until they admitted what they did and for how long they did it. The end result is we got a few hours paid for affected drivers. One of them was extremely upset that a driver reported him, he felt betrayed, ha. The looks on their faces when I caught them in their lies AFTER they constantly preach how we need to have good communications was priceless. It also pays to have a good relationship with the OMS to help you pull up delivery info on possible "ghost routes" (two DIADS for one driver). Also proud we got a vigilant "Mama Bear" on preload that does a very good job of documenting info on her shift. She's earned lots of income on that. Unfortunately, it doesn't seem to have encouraged the part-timers to start calling supes out. We had one P/T supe bring his own work gloves to the shift, lol. He was definitely on something and just could not keep his hands off packages. He eventually got tired of her grievances and left the company.
