PHNOM PENH, Cambodia (AP) — Cambodia’s Supreme Court on Friday upheld the two-year prison sentence of a labor union leader who led a long-running strike against the country’s biggest casino.

Chhim Sithar, president of the Labor Rights Supported Union of Khmer Employees of NagaWorld, had originally been convicted in May 2023 of incitement to commit a felony.

She had been leading a strike that began in December 2021 to protest mass layoffs and alleged union-busting at the NagaWorld 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 amid financial struggles related to the coronavirus pandemic.

Some dismissed workers continue to hold regular protests, appealing for Chhim Sithar to be released and for them to get their jobs back, Am Sam Ath of the rights groups Licadho said Friday. More than 200 others had accepted compensation under the labor law and dropped their demands, the Ministry of Labor and Vocational Training announced in December 2022.
