Depends on how bad your coworkers are and how bad they need you.
In my center it seems you would need to average around 3 misloads every day (or 8 in a single day) before getting on management's radar.
Load quality is awful. That my average loads pass as "a graceful act of god" to a portion of cover drivers really shows that off.
Of course. If everybody worked like me or some of the old-timers... they would have to slow down the unload and hire more preloaders
