To manage a belt, one has to be trained correctly, and last time I checked nobody is trained correctly. Ask anybody on here about someone actually being trained correctly. The only time someone is trained correctly is if a driver is training somebody, cause they know the ins and outs of how the job is supposed to be done correctly.
Training isn't taken seriously at my hub. I learned everything that I know now gradually over time with observation and self experience wether it was at belts, unload, or sort. Sups can care less about training properly; they will always try to give hourly's the run around for some bizarre reason.
