I think it's time to consider operational and non-operational staff going their separate ways when it comes to negotiations on t&c's.
It's unfair, and frankly selfish of the atcos to expect non-op staff to support them in their claims when expectations on pay and pensions are obviously so wide apart.
Atco's should do the decent thing and breakaway to allow office staff and other non-op personnel the freedom to accept deals offered by the company that operational staff are perhaps reluctant to commit to.
