But that's no real substitute for spelling and grammar is it? Independent self-employed trade's people need to have good spelling and grammar because they are in charge of writing all of their workplace's documents. It has nothing to do with what they do, but rather necessity. I once saw official Foxtel literature claiming their offer expired 31-9-05. I immediately thought "what idiot thought there were 31 days in September?" They're supposed to be a 10-year old giant corporation!I was pointing towards hands on trades, some of them can't spell - however could fix something before you could even start your car or paint a wall.
