It's a matter of relative power and a willingness to use it. TSH failed guys by giving them something that was not trained. (Usually having to do with a holding pattern exit.) Quick training, quick and short recheck and we sent them on their way humiliated, embarrassed, and scared to go against us. After we ruined their future careers for at least the next 5 years we owned them. They were also scheduled to get their signing bonus after IOE and we brought them in and told them they had to sign the updated agreement where they would not get the bonus until, if I remember correctly, a year after IOE and if they upgrade before that they would not get the bonus. To top that off we had forced upgrades before that time so in the end there was no bonus, other than what the rotor guys got for training. (Just for the record, the original agreement was still enforceable over the replaced agreement, even if the person signed the agreement, because there was no "consideration" given for the change.) Everyone signed the agreement because we made it clear there would be repercussions if they didn't.
TSH has made it clear that they are not out to make friends, they don't care if you say bad things about them, they just want your money. We offered the pilots 65,000 bonus to come here and they knew before they ever signed the agreement that we would try and F them over and not pay them. They could have told us to go to hell and not signed the change. They could have brought a lawyer in and actually got the money. Don't blame TSH for playing hard ball.
Not one guy who goes to Gojet can say he didn't know what he was getting into, they know but they still come.
