The finger was very firmly pointed at the unions as being the ones who rejected a core deal and each went their separate way for divisional deals.
I'm don't believe that for one minute. In fact I seem to remember the Prospect briefing has a slide where they state that NATS refused point blank to do a NTUS deal.
Porkies from management I think and probably not the first or last time on the matter.
Time they had the guts to stand in front of the staff and admit it.
