Teachers in Portland, Oregon's largest school district, voted Wednesday night to authorize a strike, setting the stage for a walkout that could disrupt classes for nearly 48,000 students, union officials said.



Portland's 2,828 teachers have been engaged for months in contentious off-and-on negotiations with the district on a new three-year contract, and the strike authorization vote clears the way for a strike on February 20 if no settlement is reached, the Portland Association of Teachers said late Wednesday.
