The other evening a UPS Supply Chain Solutions tractor trailer was observed inbounding at a package hub for at least unload and possibly more. I overheard several persons discussing this and one remarked 'There go more UPS jobs' in a cynical sort of way. Another was heard to say' Naw, he's just here doing that zone skip stuff.' Then another chimed in 'How do you know it's actually zone skip?' I gotta tell you UPS SCS's role was never really clear to me before, but now I'm even more confused after listening to these fellows discussion. Perhaps someone could shed some light?
