The union held a loud demonstration at district headquarters Friday that ended with the arrest of 46 protesters who were blocking traffic. Teacher's union president A.J. Duffy was among those arrested.
Teachers also marched outside schools before class started for an hour to protest proposed budget cuts and layoffs, then reported back to classes.
The efforts are to voice their opposition to the LAUSD decision to authorize layoffs that could cost thousands of teachers and school employees their jobs and increase class sizes.
District officials went back court on Thursday seeking a more extended restraining order against the teachers, saying they were concerned that teachers would take part in intentional acts to cause a work stoppage, but the judge refused to extend his orders any further.
