In June 2020, three days after forming a factory-level union, 11 union officials were informed by Greenfield Industry in Cambodia the company could not renew their employment contracts due to a lack of orders and poor performance by the workers. The local union president has disputed this and said the workers had been completing their tasks on time and receiving the daily bonus.

According to unions, Greenfield Industry threatened the union officials, telling them to resign from the Coalition of Cambodian Apparel Workers' Democratic Union (C.CAWDU) or face repercussions. The local union president, vice president, secretary and treasurer were dismissed as they refused to sign the letter. Six union officials signed the letter and quit C.CAWDU under duress.

Greenfield Industry reportedly produces garments for Irish retailer Dunnes Stores. C.CAWDU has called on Dunnes Stores to stop union busting in its supply chain in Cambodia, and ensure that four dismissed union leaders are reinstated to their original positions at Greenfield Industry.

In September, Business & Human Rights Resource Centre invited Dunnes Stores to respond. It did not.
