I know of a few cases where the Manning 'retention measures' have backfired and driven away guys who were minded to stay. All of them had changed types to bring experience and instructional qualifications to the gaining fleet.
Having marked-time during a delayed conversion and frontline work-up they are now being asked to waive their option points in order to 'accept' another RoS for the privilege of moving to the other seat. All of them are saying no and are trying to stick to the original RoS imposed on them for the OCU. Most of them have not done a single day of service without being shackled with a restrictive RoS. Indeed, being flexible enough to move types, roles and instructional duties just gets people penalised when compared to those who do just one OCU and then stay put.
The net result is the frontline gasping for the experience they need whilst a cadre of guys hold firm to their original deferred option points having been mis-sold an RoS.
