Workers strike for second day at nine U.S. oil, chemical plants

Houston, USA: Union workers were on strike for a second day on Monday at nine U.S. refineries and chemical plants in an attempt to force oil companies to sign a new national contract covering laborers at 63 plants.

The walkouts were the first held in support of a nationwide pact since 1980 and target plants with a combined 10 percent of U.S. refining capacity.
