I'm currently a loader and an air driver (Saturdays and some weekdays). There are some bids up for full time driving positions, and I was thinking about putting my name in. I need to make more money for my family, but I feel a little apprehensive about the change. Would I lose my seniority pay for loading? If I cover for other drivers, is there a guarantee to get a 40/hr week? I realize I would not start out with my own route. Thanks in advance.
