Sir Percy, does that make you one of the crusty old officers that actually believe that our JNCOs are chavs?
Having just been awarded my second degree (one Physics, one Philosophy) I don't think my Comprehensive education is all that bad either! I'm sure your comments were light hearted, though.
Not sure which Service you're with, but in the RAF our Cpls are professionals that have a range of sensible opinions on contemporary issues. Most are also a pleasure to chat to over a few drinks. None of my staff are 'chavs'.
Perhaps the lack of understanding and trust in your subordinates that you are showing is a factor that contributes to our top-heavy command structure in the Services.
