Los Angeles teachers poised for strike on Monday

ROUGH CUT (NO REPORTER NARRATION) More than 30,000 Los Angeles teachers are set to go on strike on Monday, impacting some 600,000 students in the country's largest school district.

United Teachers Los Angeles has called a strike for its members in the city's 900 public schools if an agreement is not reached over such issues as pay, staffing, and class sizes.

But the teachers union delayed the walk-out after officials with the Los Angeles Unified School District said they had not been given a legally required 10-day notice of the labor action.

A judge refused to rule on that issue on Wednesday, saying that the UTLA's court papers had been incorrectly filed.

Superintendent Austin Beutner says district officials are doing their best to avert a strike.

The union is calling for a 6.5 percent pay raise, more librarians, counselors and nurses on campus, smaller class sizes and less testing, as well as a moratorium on new charter schools.

Negotiators for the Los Angeles County School District, have countered with a proposed 6 percent salary hike with back pay and $100 million investment to hire more staff and decrease class size.

The district has urged teachers not to strike, saying that it would hurt students who returned from winter break only on Monday.

In the event of a walkout, district officials have said they would be able to fully staff classes with administrators and substitute teachers.
