More than 20 Caltex workers resumed their strike in Phnom Penh…after U.S. oil giant Chevron asked them to sign a document promising they would not protest in the future. A 10-day strike by workers seeking a minimum monthly wage of $160 ended…with an agreement that Chevron...would raise their salaries by $20. However, Chevron angered some workers by asking them to sign a document promising not to participate in any further strikes, protests or work stoppages…Chevron spokesperson Chanlek Than said in a statement that the company hoped the remaining strikers would begin work again immediately. “Our offer set out steps to resolve differences in the future in a constructive manner which recognize the employee’s right to voice their concerns,” she added.
