I stand corrected.
The banding WILL be achieved by accelerated progression up the spine points. Those at the top of the scale will not miss out as they will move onto the (currently unused) spines above the existing ATCO 2 scale. Don't know how it will work for ATCO 1s. So you are moving up the spine points but you are no closer to the top of the scale than you were.
The people who may miss out are the T&Ds who are not yet on the ATCO 2 pay scale. I don't know what arrangements have been made for them.
