I don't think it's snobbery, rather for many of us who have cleaned windows for 20+ years, the chance to work safely as we approch 50 is worth the payout.
The truth is once you have used WFP and got your head round it it's a breeze.
You do however have to deal with the mind-shift in how you approch work.
25 years ago I became a window cleaner and stayed a window cleaner priding myself in the fact that I could get to any window to clean it and if thats what the customer wants...?
I am no longer a 'window cleaner' rather I am someone who makes money in the easiest way possible using the skills and tools that I have.
That happens to be by cleaning windows usng a wfp.
I no longer feel the need to find a way to clean every window before me. I now start every day saying "What is the easiest way I can make the most money today"
I spent 18 years on ladders and now I've found a easier way to make money. There is no snobbery to it simply looking after myself.
We do tend to get evangelical about it, but then again, if you found something great you would share it.
When it comes to safety and your insurance, for me, it's a no-brainer.
I can also see that over the last 25 years the world has changed. In 1983 the seatbelt law for front seats was introduced, in the back seats it was 1991. Laws change and regulations get tighter, they rarely get relaxed. Litigation and compensation have also changed thing. In 1983 no one would have sued an individual for an accident, they wouldn't have known how to, now anyone can easily.
When I started the small print for PL was minimal, basicly if you had an accident and damaged someones property they would pay up.
Now the small print does everything to get out of it, including using wording that is deliberatly vague.
From a outsiders point of view, and I include most newbies, window cleaning looks simple and easy to set up. From a 20 year + experience point of view it has become a more complex job.
If you went to any other trade such as plumbing for example they too will tell you that standards and techniques have also changed, its what happens in any trade. Window cleaning is no different, its changed.
Some old time tradders will never change to wfp but, in my opinion, they miss out on an easier life.
