The United Kingdom’s National Health Service is funding exploitative working factories in Malaysia, according to a new investigation by The Guardian.

The factories allegedly subject migrants to forced labour, overtime, debt bondage, withheld wages and passport confiscation.

Workers tell reporters they are trapped in factories working 12 hour days, seven days a week, with only one day off per month.

Top Glove and the WRP supply the NHS with 1.5 billion boxes of medical gloves annually.
