JANUARY 22: Educators, parents, students, and supporters of the Los Angeles teachers strike wave and cheer in Grand Park on January 22, 2019 in downtown Los Angeles, California.Thousands of striking teachers cheered for victory at the rally after it was announced that a tentative deal between the United Teachers of Los Angeles union and the Los Angeles Unified School District heavily favored educators' demands including a cap on rising class sizes, funding for school nurses, and a significant pay increase.
