Classes are scheduled to resume Friday in the Los Angeles Unified School District after a contentious three-day strike and ongoing labor talks between workers, teachers, district and city officials.

More than 400,000 students in the nation’s second-largest school district will return to school after the impasse saw more than 60,000 workers hit the picket lines demanding better pay and benefits.

“We are excited to welcome everyone back at school. Thank you for your patience, understanding and collaboration as we navigated through this week,” school officials said.

Why were LA school workers on strike?

The short strike came after more than a year of negotiations with no sign of a deal. The stoppage was led by the Service Employees International Union (SEIU) Local 99, which represents about 30,000 school employees including bus drivers, custodians, cafeteria employees, campus security, teaching assistants and aides.

The union wants the district to tap into its billions in reserves to provide a 30% raise and a $2-an-hour equity wage increase. The union said the average salary of its members in the district is about $25,000 per year. That salary would currently qualify as “extremely low income” in Los Angeles County for a single-person household, according to federal guidelines. 

Many of the striking workers are part-time employees seeking full-time jobs.

Will Los Angeles school workers go on strike again?

It’s not known. The union and the district are negotiating along with Los Angeles Mayor Karen Bass and her staff now participating in the discussions, Blanca Gallegos, a spokeswoman for Local 99, said.
