Walk Free+MSA incidents remediation (revised)+CENTRICA STORAGE LIMITED+2021+Discussion
Replaced source as initially cited source was not MSA statement
p. 5 "...where they (suppliers) fail to comply with our terms, they will be required to take steps to remediate, or agreements may be terminated."
The remediation is not explicitly for workers. Seeing there are many different things that fall under remediation as per the UN Guiding principles, which do not all mean exploited workers are remediated, this disclosure is too vague for it to be assumed workers will be remediated.
