Garment factories that supply to global brands such as coffee giant Starbucks and sports gear maker Bauer Hockey were raided by police on Thursday and ordered to compensate hundreds of workers after an expose found illegal underpayments.
A Thomson Reuters Foundation investigation published last week found that at least 26 migrant workers from neighbouring Myanmar were paid less than the daily minimum wage of 310 baht in the western region of Mae Sot.
The raids, conducted by an anti-trafficking task force, government officials and police, targeted two factories. Pol Lt Gen Jaruvat Vaisaya said the owners of both factories were ordered to pay back wages owed to workers.
"The owners of both factories confessed that they paid workers less than the minimum wage," Pol Lt Gen Jaruvat told the Thomson Reuters Foundation by phone from Mae Sot following the raids.
Cortina Eiger, which runs one factory that produces apparel for Bauer Hockey and employs about 600 workers, had not given workers the minimum wage, holiday pay or sick leave, he said.
The Cortina Eiger factory owners were ordered to pay an estimated 45 million baht to 600 workers within 30 days or face prosecution. Under labour laws, failing to pay the minimum wage is punishable by up to six months in jail and a 100,000-baht fine.
Authorities were in the process of calculating how much would be paid to 11 workers found at a factory run by Kalayanee Ruengrit, which produces aprons for Starbucks, the police said.
"Both factories have promised they would not lay off any of the workers," said Pol Lt Gen Jaruvat, adding that any company that fired its workers "without a reason" would face hefty fines.
The two factories were not immediately available to comment.
Bauer Hockey and Starbucks last week said they were investigating but were not available to comment on their probes.
Siwanat Petchsringoen, manager of the Federation of Thai Industries in Mae Sot that has 130 members in the region, said Cortina Eiger had vowed to pay the minimum wage to its workers.
The Human Rights and Development Foundation, which provides free legal aid to migrant workers and victims of human trafficking, questioned whether the raids would offer a long-term solution to the issue of labour exploitation in Mae Sot.
"It might cause factories to have more standards, but it also might cause them to look for other ways [to exploit workers]," said the charity's chairman Somchai Homlaor.
The raids — which were led by officials and cops from Bangkok — could also hurt the relationship between civil society groups and state representatives in Mae Sot, Mr Somchai added.
Somboon Trisilanun, deputy director-general at the department of labour protection and welfare, said the government was planning to send a taskforce to inspect a further four factories in Mae Sot, but did not provide any timeframe.
