Dude,
I feel entirely sorry for you and your situation, it's one I have just got out of slowly,
Flying schools think that some how normal legal working practices don't apply! They are all con artists and will abuse us FI's for what ever they can get out of us....
I have maintained for some time that if the FI's of this country had there own union, and stood very firmly together on T+C's and Pay then we would get more respect and better treatment...but now that wold be too hard for the likes of BALPA to sort out or assist with now wouldn't it?
Good luck Dude, I hope it gets better for you soon, I'm with you all the way..
