Thousands of Cambodians workers at Hong Kong-listed casino company Nagacorp have gone on strike for higher pay and better working conditions.

About 3,000 workers joined the strike in front of the NagaWorld hotel and casino complex in Phnom Penh to demand higher pay of $300 a month for hotel staff and $500 a month for those on the gambling floor. The striking workers said wages now start at $150 to $250 a month.

They are also seeking the reinstatement of their union president, Chhim Sithar, who was suspended in September. One of the strikers, By Kunthea, who has been working at the casino for 19 years, said the company had warned employees in a memo they would be fired if they went on strike.
