That's sad to hear. Surely the workload is a function of:
1. The number of serviceable airframes.
2. The number of instructors and flight staff cadets.
3. The number of flyable days/hours.
4. The amount of paperwork required.
That will determine how many cadets you can fly, which should be tuned to meet the expected workload of the volunteer staff?
I know there will be pressure from Wing HQs to keep sending cadets, but its up to the OC/CFI/Adj to say 'no' when the workload gets too much. For example if you have an expectation of 500 cadets a year, but in reality you can only manage 350 due to issues 1-4 above - well guess what, 350 it is?
I would suggest that burning the candle at both ends, as you describe, is a recipe for disaster!
One last question, if I may? Without being too specific, is the VGS at a remote site or on a station/camp? If the workload is too high and you're on a camp, then why doesn't the OC ask the stn cdr or camp col for some help? They may be able to find help with paperwork and assurance work by seeking out volunteers from the stn/camp's permanent staff as a secondary duty. Personally, I would far rather help on a VGS than be a Mess Sec or OIC Barrack Block!
Just my two-penneth that might, or might not, improve things.
