All the drivers I have talked with from the other carriers union and non union that don’t work the dock get paid their hourly rate while waiting for the loads whether it be napping in their truck or waiting in the drivers room . Of course if only driving over that set amount of miles . Union as far as ABF , YRC , New Penn and Holland do not work the dock regardless of miles . I have heard UPS freight has just gone that route as well , but also heard some UPS freight guys do work the dock . I haven’t seen any to ask so not 100 % on what is going on st UPS
