From The Los Angeles Times: A Los Angeles County judge has prohibited the city's teachers union from staging a one-day strike this week to protest layoffs and other budget-cutting proposals. The judge found that the United Teachers Los Angeles contract explicitly bars a strike. He also cited concerns about student health, safety and welfare in granting the restraining order against Friday's planned walkout. Because of a budget shortfall, more than 2,500 teachers without tenure could lose their jobs July 1. About 2,600 non-teaching employees also could lose jobs.
