It is the third day of the statewide teacher walkout and a huge showing of Red for Ed supporters at the state capitol Monday.
Many schools districts in southern Arizona decided to close its schools again Tuesday.
"We got almost 1,300 teaches that have called out for tomorrow," said Dr. Gabriel Trujillo, Tucson Unified School District's superintendent.
Dr. Trujillo announced a short-term plan last week if TUSD schools were shut down for three days.
"Tomorrow marks the first day that we have the first school that has actually run out of instructional time... Warren Elementary School," he said.
The Governing Board will meet Tuesday night to discuss putting the district on a non-paid closure, possibly changing graduation dates and will have a better idea of whether additional instruction days are needed.
"If we move into a long-term shutdown of the district, a non-paid furlough situation, we are going to have several hundred and thousands of employees affected by those three or four days deducted from their paycheck," he said.
Despite TUSD schools being closed, he says cafeterias will still serve food.
The Tucson Education Association President Jason Freed says they plan to be back at the state capitol again Tuesday and Wednesday to rally.
"We are showing up because we are saying show us the details," said Freed. "Where is the money coming from, is it sustainable? And if he has got this great plan then just show it to us... bring it to the floor... let's be part of this discussion."
