When the rollover from CFNES/CFNOS to NFS(A) happened, they training system was gutted of 'redundant' positions to top up the fleet.
The concept as briefed at the time was that if we were short an instructor, we'd be able to CFTPO them from the fleet...except that's now how VCDS manning priority works...and the leadership didn't listen.
So.
As an example, the NET(A) (now W Eng SONAR) instructor cell went from 13 people, it became 5.
From 1x PO1, 5x PO2 and 7x MS, with a separate Standards Cell to support....that section became 1x PO2, 2x PO2, 2x MS, with the PO1 being the 'Standards(Internal)'.
When I had 12 instructors working for me, I could support 4 courses, with 2 instructors each, the other 4 instructor positions enabled redundancy to allow leave to be taken outside of Block leave, MATA/PATA, someone could call in sick, we could send 2 instructors to Quebec to develop new Computer Based Training, I was able to send 1 instructor to Chile on an exchange program, and, we regularly allowed our MS/PO2's to cover off a buddy on a ship that needed a week off from sailing for something personal that came up.
Having 2x instructors per class ensured that we were covered off for safety when working on live powered systems doing trouble-shooting.
Now, with 5 instructors filling the spot where there used to be 12, there is no redundancy, there is no break, and there is no ability to surge training to support 480+ W Eng JR trainees cycling through the school in a 2-ish year period.
Good luck to the RCN leadership of today trying to un-Knipple what's been done.
