PHNOM PENH, Cambodia – Workers at U.S.-owned Caltex gas stations in Cambodia went on strike Monday to demand higher wages and better working conditions, according to a report from the Associated Press.

A strike leader, Sar Mora, said at least 250 Cambodian employees halted work, forcing at least 17 of the country's 26 Caltex stations to suspend operations. Caltex, owned by Chevron Corp., is considered a premium brand in Cambodia compared to local competitors, whose prices are lower.

Sar Mora said workers were demanding a minimum wage of $160 a month, up from the current pay scale of $100–$130. They are also demanding a one-month annual bonus, an annual party and daycare facilities for children.

Chanlek Than, a spokeswoman for Chevron Corp., said it is working with "local authorities and union representatives" to resolve the dispute.

"We are disappointed that our unionized service station colleagues have taken the drastic action to stop work instead of following legal processes to resolve the matter that would have enabled us to continue the supply of fuel products and minimize inconvenience to the public," she said in an emailed reply to a query from the AP.

Rising expectations among Cambodia's industrial and service workers have fueled labor unrest, with laborers in the country's massive textile sector staging strikes and demonstrations late last year and in January for a higher minimum wage and loosely linking themselves with the political opposition.
