I'm a part time dock worker at UPS Freight. Been working 8 to 24 hours a week for the past 11 months and am about to get my benefits. In the past week we had a new driver transfer to our hub, we already have too many drivers, and if a driver does not have a route he can work the dock and push us out of our shift. I have not worked for the past week because drivers are working the dock. What can I do?
