Ive never used excuse of health n safety when i switched. But then in past i spent 6yrs in sales and so i just sell new way to them. Sell the benefits to them. If your confident in your ability and the product, then your 95% there. Depending which sex u speak to, difference of power tools n normal tools or hand washing to a washing machine, bla bla bla etc.
I was going to go down line of trolley n blade downstairs. I was adviced not to, as most switch to a van system as soon as they can. Im really really glad i listened. After now a yr on wfp, im filled with dread of thinking what i would be like if i didnt listen!
A friend of mine is keen for trolley system, filled with all same ideas as i had. Hes coming with me for a day to see how its done n gonna talk benefits of not lugging bucket, mops, squeegees, barrels of water, stopping to fill up, stopping to switch to traditional, dragging the trolley whilst holding pole n carrying a bucket etc if your work is all close nit.
