Thats's a good point there Bearman mentioning training, it's up to the Backdoor section manager or in todays situation backdoor Team leaders to incorporate the appropriate training Bronze, Silver & Gold.
What i believe happens in many stores including my store is that there arn't enough staff to cover the shifts needed, so when a lorry comes into deliver at a store the usual backdoorman is off sick & no-one backdoor trained is there to cover that shift, so MM will bring someone from the produce section to unload the delivery, who are seldom trained or given PPE for the job. If they were to have an accident stresco will wash their hands of it, even more so if a driver was to bring down a gate post whilst he or she shunts through the mess of the yard because no one has been able to do it that previous morning, then MM are or should be liable because they're not doing their job of insuring the backdor is clear>
As a backdoorman i apreciate that my store is not easiest of all stores, i always make sure i stand in the proper position so the driver can see me in their mirrors, i always wear my vi-viz jacket, if the driver is looking the wrong way when backing in that's their problem if they take out the shutter runner>
