You choose what tools to use. Not the custies. I'm trad, but if I lived n UK, I'd be 100% WFP.
It's a nonstarter here for my needs.
A point worth making is, why do WFPers want trad guys to swap? What difference does it make to you? It's the same old same old "ladders will kill you" and in the next post "Where are all these new cleaners coming from?"
The easier it is to get into window cleaning, the more people will take it on as an income. In the past, you needed to be able to work off a ladder, at height and left and right handed. A certain amount of skill was needed, and the ability to clean insides. (Now there's an idea!!)
I assume it will take years until the trad guys retire or swap to WFP. So until that happens, we'll just have to use what we want eh?
Anyway, when everyone is using WFP in 2095, we can all moan about the summer brigade and undercutters, and the guys working out of surface vehicles instead of the new airborne vans etc etc.
