 The return to classes in the midst of the coronavirus pandemic has been the motivation for debate, affliction and worry for teachers and parents across Brazil. In São Paulo, the planned return to school activities on September 8th, despite the increase in confirmed cases of COVID-19 in the state, led teachers, unions and people's movements to take to the streets on Wednesday, July 29th. They gathered outside Murumbi Stadium in São Paulo to carry out a car caravan to the seat of the São Paulo state government. Their cars, however, were blocked by the military police. Teachers, health care workers, social movements and supporters decided instead to walk to the seat of government, but were again blocked by police. The protesters were not able to engage in dialogue with the state government. The president of the Union of Teachers of Official Education of São Paulo State, Apo USB and the state deputy for São Paulo, Maria Isabel Acevedo-Noronia, called the position of the São Paulo government authoritarian. Governor João Doria again shows his authoritarianism, blocking educational workers and healthcare professionals from Apo USB and the Health Workers Union access to the Banderantes Palace. They do not even allow us to ride by foot, but we will not give up. Our struggle is in defense of life against the return to in-person classes for the recognition and valorization of the health care workers and the issuance of the emergency aid to temporary teachers without salary, she confirmed. CUT São Paulo president Douglas Isso also criticized the police blockade. This caravan is a legitimate mobilization against the return to in-person classes in the moment when COVID-19 cases continue to rise. A struggle that is not only of the teachers, but of all of society, since the return to classes without health care beyond increasing the possibility of contagion puts at risk not only teachers, but students, parents, functionaries and their families.
