Workers at a shuttered apparel factory in the Cambodian capital Phnom Penh are maintaining a 24-hour vigil at the facility, claiming they are owed US$200,000 in unpaid wages and benefits.

The workers – who hope to catch the managers if they return to collect machinery or other assets – believe the Kingsland factory closure in December was engineered to enable a new factory to open, employing temporary workers without union representation.

Now a number of international labour rights organisations, including Clean Clothes Campaign, are supporting the workers.

They are calling on retailers Walmart and H&M – which they say were supplied with underwear by Kingsland – to ensure that Kingsland pays all monies owed in accordance with Cambodian labour law.

The statement, signed by 17 organisations from around the world, also urges “immediate and transparent” investigations to be carried out by the retailers.
