The Los Angeles Unified School District and union leaders announced Friday they reached a deal on pay raises for bus drivers, custodians and other support staff after a three-day strike that shut down the nation’s second-largest school system. The deal includes a series of retroactive raises going back to 2021 that will collectively hike worker pay by about 30 percent, and provides workers with a one-time $1,000 raise, sets the district’s minimum wage at $22.52, and creates a $3 million educational and professional development fund for union members.
