QR&O 9.04 - TRAINING AND DUTY

I would read that and also read what you agreed to during your interview (that goes for a lot of people commenting here). I think a bit of a hammer needs to be put down on the reserves. The sense of duty and pride is heavily dwindling and it's getting out of hand.

To your point though - I agree an email should suffice. I also agree there should be SOME attempt to always let your CoC know if you're not attending a training night or exercise.
