On September 12, in the capital of the state of Paraná, Curitiba, grafittis were installed on a bridge and a wall of a Portuguese corporation to mobilize for the general strike, which were signed with "Liga Operária" (workers' league).

On the bridge was the slogan "ABAIXO A REFORMA PREVIDENCIA GREVE GERAL!" (Smashes the pension reform - general strike) to read, on the wall of the corporation was the slogan "GREVE GERAL DE RESISTENCIA NACIONAL!" (General Strike of the National Resistance) attached.


A few days before, on 7th September, thousands of placards from the 4th plenum of the unions were attached with the call for a general strike in the city of Belo Horizante, the capital of the state of Minas Gerais. Most of the posters were placed along the route of the march to the Brazilian Independence Day. Members of the Liga Operária, which is also part of the 4th plenum of the unions, distributed leaflets during the demonstration and mobilized for the general strike.
