Reversing without banksman = possible sacked

we have to use banksman or as our firm calls them “reversing assistants” It helps if you have the same crew mine changes everyday at the moment so you cant build a bit of team work up my colleagues who do have a regular crew have it sussed as they know how each other operates I think its a good idea though as you cant rule out someone running from behind a parked car or agressive drivers and when you are in a busy town 3 or even 4 sets of eyes are better than 1
