Ratatat,
Have you spoken to your union reps about this? Do you have a union now? Wasn't 'Red' involved in the ANSP transition? He certainly believed in his workforce having "a strong union". I have the document with that quote in the loft.
If EGKK GMC/GMP is that busy, (and I don't doubt that it isn't), surely another 'sector-split' is required.
What about Chirp, or the MOR system?
