If you work at UP and you're not a manager, chances are that you spend most of your time complaining about your managers. Believe me when I tell you that managers detest you as much you detest them, and they probably detest UP even more than you do. The simple solution for all the agreement people is to go back to school, get some marketable skills, and find a better job at a better company.
Pro tip: don't give UP any notice when you quit. It does nothing for you. They also stop paying you the day that you give notice.
