This isn't what techs are for, ?
Only joking and agree that your class 3 should be shadowing you and learning his trade but just like VM class 3's we cannot hold their hands and educate them any more because of overstretch. Ive got some ex VE Cpl's at the moment who have retraded as VM's but unfortunately a bit of a fish out of water. Great lads, but steer towards the electrics side jobs more which they know inside out rather than VMing. Why did powers above break things that worked well as usual.
