I have my doubts whether your post and feelings are genuine, but I will indulge.

If you want to work in a position that you have NO say in what to do and how to do it, then the TSA is for you. It is very black and white, either to comply with the order from the local FSD, or they can dismiss you right there.

Then, there's the flying public. 80% of an individual airline's revenue come from 20% of its flyers. That means you get a boatload of frequent fliers. Many of these frequent fliers (including myself) are used to passenger-friendly experiences with the TSA. When we see inconsistencies, we point them out. Some do it verbally, and some get complaint cards. Some do both.

About the working environment, read <a href="http://www.flyertalk.com/forum/showthread.php?t=380052">this string</a> and see how a TSA employee feels, and how sympathetic we are.

If you do a search, there have been other strings of TSA employee dissatisfaction and high turnover. At my "home" airport, Denver, they are resorting to hauling TSA folks from Colorado Springs for overtime and are consolidating screening lanes to use fewer staff (and slower lines).

I know teaching is difficult nowadays, but I would seriously consider the Hertz or Avis option you mentioned.
