UAW to strike GM?

The UAW is planning a 10 p.m. phone call to union halls across the country to announce whether they will strike General Motors Corp., union sources said today.

A deadline on GM's contract with the United Auto Workers union expires tonight at 11:59 p.m. If there's not an agreement, the union could decide to either strike or extend negotiations with the automaker.

The union has been working since Thursday to mobilize thousands of blue-collar workers to be ready for a walkout.
