According to the search results, the Los Angeles Unified School District (LAUSD) is on strike this week. The strike is scheduled to last for three days, from Tuesday through Thursday. The strike involves tens of thousands of union workers, including teachers, bus drivers, custodians, cafeteria workers, and other support staff. The strike is in protest of unfair negotiating tactics by the school district, and the unions are demanding wage increases, more full-time work, and more staffing for student services. The strike is expected to impact more than 420,000 students in the LAUSD.
