The latest contract we have 'won' (sounds a bit like ebay where they say you've won the item... that you are paying for) does not exactly have good repercussions financially for either the pension pot, or NATS collectively, or dare I say it NSL if NATS are looking to get rid.
Basically, as far as Ts and Cs (including pension) are concerned, we're (NATS collectively, old scheme members and new) screwed.
