Letsgoandfly,
I agree with you totally, there's no natural justice in chucking people out while simultaneously recruiting for the same job. Unfortunately I strongly suspect you'll discover the armed forces have exemptions from employment law that were put in place to allow the business of defence to be carried out sensibly. Exemptions that are now likely to be misused (in spirit, if not in law) to allow the RAF to do what it feels like. You've got my sympathy (genuinely), but all good siggies know exactly where THAT word sits in the dictionary, don't we?
Personally if I were one of the keen types posting here hoping to discover that recruitment is going to continue I'd now go dowse my head in a bucket of water, then give myself a good slap.
