They are also contractors and do these visual tuck ups to customers with flyers, get a free inspection of your electrical installation, we will pull it to pieces and quote 1000/s to "make it safe"
A guy who worked for me went for an interview. He was asked a few electrcial questions, difference between earth and bonding, how would he find a fault on a ring final circuit..................that was ok
Then they asked him how would you park a van/car in a car park. He thought it was a trick question, but he was told that you reverse into it, as when you are leaving the space there are blind spots and you can endanger people walking behind you, he said how would he get the tools out if the rear was up against another car.
Another was how would you walk down a stairs if you had a tool box and talking on the phone. You must end the call as you must hold onto a rail for health and safety reasons.
The best was that at all times sleeves must be rolled down, he said that was ok as he liked polo type shirts with short sleeves, but they told him no all uniform was with long sleeves for health and safety, where he got up and said if they were the last employers on earth he would starve.
