mm_flynn,
Is that the out of step part or the can't change part?
No, it's more that part that all the ills that IO540 perceives in the ATC system are down to unionised control staff somehow causing them.
I can only assume that he's had difficulties with unions in some other respect in the past for the ATC argument blame always to be laid at the foot of trades unions.
It's just a bit of a stuck record that, in NATS at least, has very, very little basis in fact and it would be nice if just once he acknowledged this rather than routinely perpetuating such rubbish over all over the internet.
