I've been loading the same truck for over 3 years now and I've never been sent to another truck unless we were understaffed, which is rare - usually they bring in temps or unloaders. Seeing all the new hires and other loaders constantly being sent to other trucks has me worried that other supervisors don't want me on their PD. Or, maybe I'm the only one that can do this truck properly. Anyway, I'm thinking about trying to move up, but I'm worried that if the former is the case and I've been "blacklisted" from other trucks, maybe that would have an impact on trying to become, say, a driver or supervisor. What do you all think?
