Whenurhappy,
If you haven't come across the techie vs admin pay argument/discussion (I'm talking junior ranks here, not officers) then you either aren't in the RAF (which I know not to be true) or you need to spend less time representing HMG at cocktail parties and more time paying attention to what is happening around (or should that be "beneath") you in the RAF.
No doubt the issue, and resentment it causes among the techie trades, isn't a talking point on Shrivenham courses?
