More than 30,000 Los Angeles public-school teachers began a long-planned strike on Monday, pressing demands for higher pay, smaller classes and more support staff in the schools.
The strike effects roughly 500,000 students at 900 schools in the district, the second-largest in the nation. The schools will remain open, staffed by substitutes hired by the city, but many parents have said they will not send their children across picket lines.
The impact of the walkout is likely to ripple across California and the rest of the country. Teachers mounted large-scale strikes in six other states last year to protest low pay and demand more money for public education.
