Over 30,000 teachers went on strike in Los Angeles County today. The Los Angeles Unified School District (LAUSD) serves 640,000 students and is the second biggest school district in the country. The last time Los Angeles teachers went on strike was 1989.

The protest follows a string of successful teacher strikes across the country. Teachers in states like West Virginia and Oklahoma — who are among the lowest paid educators in the country — have organized and participated in strikes in order to advocate for higher wages and improved conditions for students.
