I work in the 'systems' side of things - not an ATCO. ATCO's doing a VERY similar job are paid around £30k a year more than me - do the maths. All ATCO's with a validation get back in the opsrooms, back in the 80's ATCO's did the wings, FIR, flow etc so I don't think there will be an ATSA shortage, just an increased utilisation of available staff. I understand this plan is already in motion.
