P.4 "In our 2019 assessment we have further analysed the third party category of “Others” and in particular the sub-category of “Building Management / Maintenance Organisations”. We identified that when solely applying the risk criteria No.3 above (Slavery, Human Trafficking and Forced labour), this sub-category poses the highest risk due to the nature and characteristics of the business activity."
I would say "Building Management/Maintenance Organisations" actually refers to an industry/sector rather than a workforce.
