I feel for ya mate. The mob I'm contracted to now only hire almost non english speaking people, that have NFI on even how to inspect a bloody fire extinguisher. Let alone how to spot an RCD from a circuit breaker. I had to train this Philippino guy last year. At Epworth hospital too off all places. Hell of a nice guy, from what I could understand of him, and everything I told him, he just looked and nodded and said o.k. When I finally handed the reigns over, he just stood there like a stale bucket of piss.
Its already starting to cause customers to leave as my contractor often rings me to go fix the sh!t up. Seems everytime they ring I have left my care factor pants outside though.... Feb next year and I'm out for good.
This will eventually bight a few on the arse I reckon. Unfortunately, it might take a death before anything is done.
