I occasionally do some work for a company who’s policy is that while reversing all drivers must have a banksman.
Saved my bacon on one occasion. Was reversing into a customers yard and the obligatory banksman came out to do his bit. I had to do a tight reverse alongside the building to get the back doors into a far corner onto a bay.
There were some overhanging spotlights on the side of the building and I couldn’t see them as I reversed round a corner, several times I asked the “banksman” if I was clear of them, till we hear a crunch noise.
Turns out the rear corner wasn’t clear at all.
Anyway in the following investigation it turns out they had tried to save money by not training the banksman so he didn’t know what he was doing, and didn’t take it seriously.
He got the sack when really, if it were any other place, it would have been my fault.
Certainly learnt from that never to just blindly trust someone to do what they say they are doing, when its your job to be looking after the vehicle and where its going.
