That's interesting...
I was reached out to after a few weeks of silence after applying to the network manager role at Collingwood, asking if I wanted to put myself forward for this instead.
The job pack I was sent put the salary at £34420-38002, and I didn't hear back when I asked to put my name forward.
Based on the job descriptions for network manager (congrats to OP for getting that position) and deputy, the network manager is more of a director for IT, and the deputy is closer in role to an actual network manager, which makes the salary even more insulting.
What a state the education IT industry is in.
