Malaysia said on Tuesday it would file charges against Top Glove Corp because of poor worker accommodation provided by the world’s biggest maker of medical gloves.

The Labour Department, part of the Ministry of Human Resources, launched investigations into worker accommodation and hostels after last month’s COVID-19 outbreak at a Top Glove factory in an industrial area near the capital Kuala Lumpur.

It said it had investigated six of Top Glove’s companies in five states and had recommended filing charges after opening 19 probes. It did not say how many charges would be filed.

Top Glove said it was working to improve accommodation by Dec. 31, the end of a grace period for employers to meet new government rules on accommodation standards. The rules have been in place since Sept. 1.
