I can relate to what you are saying. I to have had trouble with an employer that I have had. I used to put in a lot of hours and dedication into a place where I worked only to be thanked by them Backstabbing me constantly. They were saying things like "He hasn't ernt his bars"(which upset me greatly) and that was one of the nicer things they said. That was after I had worked 3 jobs to pay for my instructor rating! These poeple were the sort that if they made a mistake rather then owning up to it they would falsify records and blame others rather then owning up to it.
Yes they were Arseholes but it is not the only industry where this sort of thing happens. I have some friends who are musucians who expierience the same thing.
The whole thing is to get out there and meet poeple in the industry and get to know who the good ones are because there are good ones out there who don't saft you. You just have to find them. Thats the hard bit.
The worst thing about instructing is that yes you do get some poeple that just do it to get hours and don't instruct and they are the types that make things difficult for those that like the job, so what you have to do is make your instructing do the talking and rise above that find a good operator and your job will be much batter.
Hows all that sound ? bye for now
