Thanks again for your replies!
Just waiting for a written job offer before I go into negotiation with my DO - I would have thgought they'd much rather keep someone who wants to stay as, to be honest, I want to leave. I am still beavering away with whatever comes along at work and have 5 secondary duties so it's not like I'm shirking or dodging work!
PTC - for what it's worth I joined as one of the last AEOps and I haven't changed my ToS at any point in my career.
Thanks again gents, have a good weekend!
