PHNOM PENH, Cambodia (AP) — A union leader freed from prison Monday after serving time for her part in a strike against Cambodia’s biggest casino has vowed to continue the labor action until justice is done.

Chhim Sithar was sentenced in May 2023 to two years' imprisonment for incitement to commit a felony, including time served before her conviction, in connection with the strike against the NagaWorld casino, the longest such labor action in the country's history.

She had been leading a strike of hundreds of workers that began in December 2021 to protest mass layoffs and alleged union-busting at the casino in the capital, Phnom Penh, and was arrested and charged after a January 2022 demonstration of dismissed employees who were demanding to be rehired.

NagaWorld in late 2021 had fired 373 employees during financial struggles related to the coronavirus pandemic.

Speaking to The Associated Press at her home shortly after her release, Chhim Sithar vowed to continue leading the strike.

"About our advocacy fighting for union rights at NagaWorld, we will continue holding strike action until we get a solution. That’s the position we have determined since the first strike,” Chhim Sithar said, sitting on the floor surrounded by relatives.

“Unfortunately, as of today, after nearly three years, our workers have still not gotten justice. Therefore, as long as there’s no justice, our struggle continues,” she said.

After Chhim Sithar’s arrest, some dismissed workers continued to hold regular protests, appealing for her release and to get their jobs back. However, the Ministry of Labor and Vocational Training announced in December 2022 that more than 200 others had accepted compensation under the labor law and dropped their demands.

“Despite relentless efforts by authorities to suppress the strike — including sexual harassment, physical assaults, and judicial harassment — the LRSU strike continues in Phnom Penh,” the Cambodian human rights organization LICADHO noted Monday.

NagaWorld is owned by a company controlled by the family of late Malaysian billionaire Chen Lip Keong. The company received its casino license in 1994 and the property is a huge integrated hotel-casino entertainment complex.

Previous labor union actions in Cambodia were usually at factories in outlying areas or in industrial estates in other provinces. The protest by the NagaWorld workers in the capital was unusually high-profile and drew police action that was sometimes violent.

Last year, the U.S. State Department named Chhim Sithar among 10 recipients of its annual Human Rights Defender Award. She was described by the then-U.S. Ambassador to Cambodia W. Patrick Murphy as “a courageous and tenacious labor union leader who peacefully advocates for the rights of Cambodian workers.”

Cambodia’s government has long been accused of using the judicial system to persecute critics and political opponents. Prime Minister Hun Manet succeeded his father last year after Hun Sen ruled for four decades, but there have been few signs of political liberalization.
