More than 30,000 public-school teachers of the Los Angeles Unified School District (LAUSD) went on strike from January 14 to 22, 2019. Protesting low pay, large class sizes, inadequate support staffs of nurses and librarians, and the proliferation of charter schools, the teachers went on strike for the first time in the district in 30 years. The strike was authorized by United Teachers Los Angeles (UTLA).
