Whether people decide to stop flying when they apply for PVR or the RAF grounds them, the end result is the same. No-one to fly the aircraft.
The no flying pay after Apr 12 issue has forced /will force people to pull the plug early.
12 month PVR terms lend a modicum of short term stability to the system from manning's perspective, but in combination with the above, it has resulted in a breakdown of trust and loyalty towards the service from many in the pilot cadre. Hence the somewhat militant attitudes expressed here and elsewhere.
In most walks of life, if an organisation is keen to stop people walking out the door it looks at the reasons why and tries to address those issues. Only the MOD tries to keep people in with threats of financial hardship or punitive job changes if one decides to leave. Not to mention the ability to force such condition for up to 18 months if they so desire.
It is true that companies in the real world are every bit as cunning and exploitative as the RAF appears to have become. But that is why employment law is there, to protect individuals from these sorts of tactics that would otherwise be rife.
Trust and loyalty. Not much of either around these days, which is a shame, because it's very hard to get back.
