A rally Friday at Pershing Square is expected to draw thousands of teachers, school employees, students and parents.
It's part of a week of protests that targeted education funding. Protesters have called on lawmakers to maintain funding levels for education.
The rally means the LAUSD will shorten the school day so teachers can attend the rally.
Other rallies are planned in Sacramento, San Diego, San Francisco and San Bernardino.
United Teachers LA President A.J. Duffy issued a statement to teachers, which said they "cannot encourage or condone such activity, as it could put our students in harm's way."
"Having said that, we in no way want to dampen the ardor of our students, their parents or the community in their desire to step up and participate in actions and activities in pursuit of preserving public education and the jobs of their hard-working teachers and health and human services professionals," Duffy said.
Teachers are scheduled to arrive downtown at about 4 p.m.
The shortened day was the result of an agreement between UTLA and the LAUSD.
