In-Cog-neeto
If you feel that way, why are you doing it?
As a punter, I want an instructer who enjoys what he/she is doing and has the ability to impart knowledge and experience to us students and not someone who is doing it because they can't get another job.
If you feel that you are getting shafted by your employeers then maybe you should start making an effort to improve your lot by getting another career.
