Five people remain missing in the Valencia region after torrential rains and flooding drowned people in cars and underground car parks, and collapsed homes.
Thirty schools were still closed, the regional teachers’ union STEPV said, leaving 13,000 children with nowhere to learn.
About 5,000 people attended the demonstration, the Spanish government said.
“We feel abandoned because, teachers, parents and volunteers have had to clean up the schools. We have seen cleaners in some schools but not enough,” STEPV spokesperson Marc Candela told Reuters.
