YES! Anything else I can answer for you?
Lets take a step back and look at the situation. It seems our On-Car Sups now-a-days were not drivers once themselves. Food for thought; Who gets the bigger paycheck, the On-Cars or the Drivers?
I have been with UPS 7 years now. I have been told that before I was with the company this was not the case. I was told the majority of the "Sups" came up through the driver ranks. Without doing the job day-in and day-out for at least a year (my opinion here) a person can not come close to having the full measure of everything we have to go through and deal with on a daily basis. That last statement goes both ways! As a driver I am not going to pretend to know exactly what my On-Car or center manager has to deal with and stress thats placed on them daily. Just as we drivers have to "deal" with our sups on 1 end and the customers on the other end, our sups have to deal with us drivers on 1 end and their boss's demands on the other end. Could the impossible dispatches we get in the morning be comming from the impossible demands our sups get hours before we arrive? Once we stop looking at the other "group" as the enemy, to be fought with at every interaction, and realize we are all in this together and that we can actually work together, this company will soar and we'll all be richer in every aspect of our lives.
To the OP- You have been presented with a wonderfull oppertunity should you chose to view it in the correct context. You have a new sup who you can take under your wing (yes under your wing as you have the years of experience in which to draw upon) and help him understand what "our job" entails. What has worked in the past and more importantly, what has not worked and why. You have a choice; Be combative at every juncture with this new sup. Or you can stop fighting just because he is in the "other group" and help him grow, thus making yourself a better person at the same time and making your life easier.
I am pretty sure the reason I see discipline as the go to action by management in resolving an issue or fixing a problem is because thats what they have been "conditioned" to expect from us drivers- confrontation or an outright fight in every interaction. We have done this to ourselves as drivers by viewing management as the enemy. Drivers are pretty damn good at making our customers happy and soothing things over with the customers when things go awry. This talent is one of the unspoken, unrecognized traits of our best drivers. We can not expect or demand this same skill set from the "other group" as they have not been given the oppertunity to develope these skills by driving for years. We can not stop using these skills once we get back to the building so, "work with them not against them."
