I take the point on expansion but there's still sustainability to cover retirements and perhaps part time contracts. We're certainly due an update that's for sure!
It could be a while, whilst they'll have a handle on retirements ( roughly), the rearrangement of the work patterns for existing part timers has only just begun, with bid closure for those involved in May. Only then will follow the handling the new (internal) bidders for PT, my guess is only after seeing demand for that will they look at external requirements ...I short I think it will be a while before any concrete news.
