Brazil: Tear gas fired as Sao Paulo teachers protest social security reform

Police fired tear gas as teachers protested against a social security reform project in front of Sao Paulo's city hall on Wednesday.

Municipal teachers have been striking since March 8 against a social security reform project proposed by Sao Paulo prefect Joao Doria, which would entail a raise of civil servant taxes from 11 to at least 14 percent.

The proposal also includes the creation of a supplementary rate which could reach 19 percent.

93 percent of Sao Paulo's municipal schools have been affected by the strike, according to local media.
