I tell the younger drivers (I started in 1975) "Do what they tell you (as long as it's not unethical or immoral), if it takes you longer, you make more money! Stay under the radar. I also tell them to let management make the decisions. If you have too many air stops, emergency conditions because of weather, etc. stay in communication with the center and let them make the decisions. Do the best you can but let them make the decisions.
I have found, after working for many different management people, that if you work with integrity and do what you agreed to do when you signed on to UPS you will prosper.
PREACH!!
