That seems to be a triumph of hope over expectation. Lufthansa want out of the bmi business so much they are going to pay IAG to take it off them. There'll be no "not on my watch" coming out of the Fatherland. Once again, people need to have a good look at what TUPE does and not not confer. The idea that TUPE makes people redundancy-proofed is incorrect I'm afraid. What you expect Lufthansa and bmi to do now isn't really that relevant as by next Friday it'll be IAG in charge and they'll do it their way.
People are getting way too hopeful as to what UK employment law will give them. The reality is that the law favours the deep-pocketed employer over the employees, and once the employer has decided to shed staff it's impossible to force them to revisit the decision. Courts and Employment Tribunals can only issue un-enforceable reinstatement orders and award limited compensation. The best hope for those facing redundancy now are the company councils influencing BA to find a cost neutral way to keep everyone on board (and it will need to be cost neutral, as IAG won't allow any department to grow it's way out of losses). Can the bmi CC come to their senses and start looking to save jobs rather than waste their time pursuing seniority?
