OCPSF told me I could not work until my terminal leave - I politely told him to shove his shiny trousers where the sun don't shine, left work on the Friday and started work the following week at the start of my accrued annual leave and before all of the remaining 5 months of resettlement I was entitled to. Good luck and don't forget to get a refund of the NI you will be paying when you are still conjointly employed by the RAF and your new employee - I got nearly 900 squid back.
