Grassed up....

Did you deliver all you jobs complete the jobs you was given?
If so what’s the problem does it really matter if you carry them or use a trolley?.
Plus the way I’m seeing it your provided with an extra man who is there to assist/help you
Yet he didn’t seem to want to help you he wanted to do it all himself. .
Also ask to see a.copy of there manual.handling procedures booklet/leaflet.
As im.sure in there there will be a weight limit around 20/25kgs which can be lifted safely on your own.
If they want you to lift carry everything yourself then why do they provide an extra man?
