PHNOM PENH, Cambodia (AP) — Workers at gas stations in Cambodia owned by the U.S. oil company Caltex have gone on strike to demand higher wages and better working conditions.

A strike leader, Sar Mora, said at least 250 Cambodian employees of Caltex halted work Monday, forcing at least 17 of the company’s 26 stations to suspend operating.

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

Caltex, a subsidiary of Chevron Corporation, did not immediately reply to an emailed request for comment.
