I started as a Ryanair employee and once I finished my line training I was told I had to resign from Ryanair and sign a BRK contract.
Did you know about that before you started paying out for your type rating? Or did they tell you once you started your line training. In the sim I assume you were not on any contract, but if you were later an employee and then forced to resign that sounds like you, and assume others, would have a claim for wrongful dismissal.
