AFPRB
Sadly these annual reports are not independent and never have been. Whilst in the good times that's less important and visible the last 4 years highlight how they are fully meshed with policy from No 11.
The RAF as a whole don't have a retention issue IMHO. Outside of redundancy periods 10% leave every year. Currently that's just over 3 000 folks. Recruitment I'm not so sure about given it has been so low over recent years and is still way off what is needed to steady numbers: currently 1800 joining annually. You can all do the math. Nice new advert so I'm sure it will be fine...
