Thousands of teachers, students and union allies marched through downtown Los Angeles on Saturday, from City Hall to the Broad museum, a month ahead of a possible strike that L.A. educators have threatened if the district doesn’t meet demands that include retroactive raises, smaller class sizes and more nurses and counselors.

The March for Public Education, organized by United Teachers Los Angeles, was meant to be a show of force to Supt. Austin Beutner, who has said Los Angeles Unified School District does not have the funds to meet the union’s demands and ensure the district’s financial solvency in future years.
