Hugh is completely spot on!.
You need to act like a dentist, ring existing clients and and organise checkup timetables, actually do this on the first appointment. "I will pop out and assess you in 12 months time for an OH&S etc....
My dentist is great at getting me to come in every 12 months, doesnt take no for an answer. I am glad he does, though I do groan at the expense but hey, I will have my teeth
The whole scary nightmare of OH&S changes on a rapid basis, so Hugh's suggestion of regular newsletters keeping a front of mind vigil should carry your business.
You are selling 'peace of mind' based completely on fear which then turns to trust Wouldnt it be nice to have that special relationship?
Share some horror stories and you'll get clients lining up as long as you dont charge $500 as hour.
I am currently suffering severe work cover issues and not because of any injury, but now over some expired pieces of paper, though the original issue was over a handrail that was 3mm too close to a wall at only 6cm of the wall (the wall wasn't quite level). Yes he did measure the entire length & breath of the silly thing.
My business has changed so dramaticaly in the last 8 years, we have different equipment, different operating proceedures, had a variety of intellect when it came to staff.
And no, it is never wise to assume Oh &S is all about common sense, because it isnt. When you have to include in your self authored business specific safety manual, elements that cover "How to sit correctly on a chair", common sense flew out the door.
