FB,
I don't believe management have been totally honest in their dealings with the union and have been bordering on negligent in their handling of it by paying less than required, regardless of trustees advice!!
I'm not sure that's quite correct.....NATS pay what the Trustees tell them to pay. I don't believe the Trustees have ever advised anything different to what has actually occurred. When NATS took the 'holiday', that was agreed between NATS, Trustees and Unions.
