"Woolworths has worked with the Fair Work Ombudsman over many years to seek to eliminate exploitation of workers employed by contractors and subcontractors," the spokeswoman said. "We have invested significant resources in implementing processes to identify and address any workplace non-compliances by contractors in Woolworths' supply chain." Woolworths has launched a number of initiatives to eradicate exploitation, including audits of its cleaning and trolley-collecting subcontractors and an independently run helpline.
