I'm not so sure how good contract churn is for ATCOs in the long-term. The new ANSP will generally need to reduce costs so it's hardly surprising when you see them advertising for ab initio ATCOs, offering lower pay and poorer pensions too no doubt.
Ehm... that happened in Nats nearly 10 years ago.. when current employees at the time voted in favour of much lower pay conditions and a change in pensions and T&Cs for the new starters.
It was the existing staff that voted for that, it wasn't forced upon them by a new ANSP!
