resettlement plus leave
So 12 months left. You will get full resettlement with your length of service. Full settlement is 7 weeks during which you can work for someone else but not be paid (except through a golden hello when you finally leave). So still 6 months adrift so you need to ask for 6 months PVR which might be more palatable to manning than asking for 4 months. Since of course you also have a full year of leave just plonked into your lap you could ask CO for permission to work in spare time which I think is hidden in an AP somewhere.
