In September 2020, approximately 250 workers at Sepia Garment factory in Cambodia joined protests over two months’ unpaid wages after the factory suspended operations during the COVID-19 pandemic in August. According to publicly available supplier information, Sepia Garment produces for Sainsbury's and Matalan.

Business & Human Rights Resource Centre invited Sainsbury's and Matalan to respond. In its response, Sainsbury’s said Sepia closed in August and it no longer has a relationship with the supplier, but understands some workers have reported not receiving the correct wages and benefits. It said it is working with the supplier to further investigate. Matalan did not respond.
