Get your self a union.
Then you can complain that the union reps (probably going to be Captains) did the deal that you are complaining about and you will have paid a percentage of your salary for the privilege.
Ask how the NATS ATCO union has improved the student member's pay and conditions over the last 10 years!
A union will not change what is being complained about here. It may be useful in certain cases but then again a good legal insurance policy would be cheaper and provide better cover!
