Well if you mean the piece of paper lying around that says that ''as PCS have yet to approve the pay deal, the ATCOs pay deal is technically not accepted and thus staff should not work additional attendances until agreement has been finalised'' (or words to that effect then yes it's been suspended!
It's a non starter anyway- I mean don't management realise that most of us have enough of the place as it is without working on our days off? Give me £1k after tax per day and I MIGHT consider doing a couple of days... anything else just isnt worth the hassle.
