I'm not surprised EvilTwins, it seems that it takes a couple of years before ordinary staff start becoming really aware of the changes implemented by these chain groups.
IT is one of the functions taken over by the AET in their academies. I suspect that unbeknown to most staff the AET commissioned a manpower audit and review of the academy and staff, maybe using one of their HR consultants. From this they have probably deduced that your academy requires less on site IT support, AET as with most chain groups have a centralised IT support service. Your academy probably also has or will have installed their online helpdesk software for staff to register IT problems. Of course, your academy will be paying for all this, including the project management costs, either as part of the annual service fees paid to the AET, or for licences, or as additional payments to the AET or third party suppliers for consultancy fees, and of course the training which will be needed as a result of the changes in systems. But you probably know all about that, you'll also be able to judge whether its cost effective and provides good support for the academy or whether its just a money maker for the AET.
The same exercises will probably have been undertaken at academy expense I suspect on facilities, curriculum and leadership. Academy start up cash is a good source of revenue !!!! If you haven't already found out the results of these, I'm sure you will before long.
I'm pleased that none of the staff from your academy have been bought off with centralised jobs or high salaries. Obviously integrity rules there. It appears that many academies find that most of their senior staff and governors are replaced eventually by chain group appointees, this gives the chain group total control, there is no one left to dissent or whistle blow.
Chain groups are obviously lucrative businesses, they can instigate the changes, plan the changes, source resources, implement the changes, project manage the changes, manage operations, design training, implement training, support and monitor operations and services, assess risk and prepare reports for management with future recommendations, all at the academies expense ...... then start cycle again.
Of course if anything goes wrong, all blame lies firmly with the academy - doesn't it.
At some point the money starts to run out .... then what. Chain group moves on to the next academy maybe !!!!
