I'm currently a qualified part time cover driver for just over a year now. Recently I just started delivering Saturday air roughly 8am to 12:30-1pm, the air rate is obviously considerably different from my ground rate. My question is my supervisor recently had me pick up a couple ups stores (which I normally do but only take air packages) and a mall pick up. The only difference is this time he had me take ALL packages including ground, since this is the case am I due my ground rate???
