UK employment law is fairly well entrenched and fairly objective, although it is open to a certain amount of interpretation. I went through a redundancy a few years ago and managed to get better terms as a result of a little research and being foreceful with my claims. But here are a few pointers.
First, the redundancy process has to take a period of time - usually three months. Although the law accepts that paying three months of pay instead is acceptable if the decision is that the redundancy is inevitable. Second, an individual is not made redundant. His job is. Therefore, someone can't be told to go and another moved into his place - which is why some pilots on some fleets may be OK. Third, the selection of candidates must be fair and follow laid down criteria such as 'Last In First Out' - although this in itself is not necessarily a selection process.
It's complex and if you feel you want to have a protest, you should seek legal advice rather than soliciting opinions here. But the MoD are no different to any employer and have to follow the law.
