but the approach jobs have a fairly long waiting list and the line starts somewhere behind me
Lets pretend that some form of experienced controller program was implemented by AirServices. If there is the shortage of bums on seats, if somebody was an approach controller elsewhere why not utilise that skill? To echo ANSA, I'm not talking about people striding in with any sort of seniority or thinking they are saving the world, simply the use of experience and knowledge to provide a service a person is licenced to provide.
