São Bernardo, in the Brazilian state of São Paulo, became a crucial setting in Brazil’s struggle to restore democracy. A strike at the Scania truck factory in 1978 began with workers’ anger over wages and the government’s misrepresentation of inflation, but it helped transform workplace protest into a wider political coalition. From the factory floor and the city’s labor movement, organizing spread into a national party and a broader effort to make the return to democracy more inclusive.

The Scania strike

On May 12, 1978, workers at the Scania truck factory in São Bernardo put down their tools as the morning shift began. Strikes had been banned since the 1964 military overthrow of President João Goulart’s democratic government. News that the government had manipulated inflation figures, understating the rise in the cost of living, gave the workers an immediate grievance. At 8:00 a.m., union organizer Gilson Menezes called the union; by noon, its president, the thirty-three-year-old activist Luiz Inácio Lula da Silva, had arrived at the factory.

When the company asked Lula to persuade the workers to return, he refused. The stoppage became the first in a wave of strikes across Brazil. Though the immediate dispute concerned wages, the action also challenged a political order that had prohibited strikes and constrained collective organization. The episode showed how a workplace grievance could become a form of political action without ceasing to be a struggle over pay and living costs.

From workplace action to coalition

The strike’s significance extended beyond the factory. During the 1970s, Brazil’s labor movement re-emerged as part of a broader response to a decade and a half of military rule. In 1973, Fernando Henrique Cardoso argued that democracy would have to be rebuilt by bringing together the social groups opposed to the military. The coalition he envisioned included professional associations, unions, churches, student organizations, study groups, debating circles, and social movements.

São Bernardo supplied an important point of convergence for that organizing. By late 1978, Lula was proposing a new political party, not merely a vehicle for union leaders but one intended to represent wage earners and poor people more broadly. A meeting in São Paulo on August 18, 1979, brought together former opposition politicians, union leaders, students, intellectuals, and representatives of one hundred social movements. The Workers’ Party was launched at the São Judas Tadeo restaurant in São Bernardo in October 1979, giving the diverse groups a shared political organization.

Political change and the city’s significance

The party used the gradual political opening to enter electoral politics. It ran candidates for the first time in the 1982 local elections and won two mayoral races. As Brazil’s democratic institutions were restored through the 1980s, the party gained control of more local governments; by 1988, it governed thirty-six municipalities, including São Paulo and Porto Alegre. In the first free presidential election since the military coup, held in 1989, Lula received 16 percent of the first-round vote and 44 percent in the runoff against Fernando Collor.

The importance of São Bernardo lay not in a single dramatic rupture but in the organizing that connected local action to national change. Brazil’s transition did not begin with one revolution that remade institutions all at once. The factory protests instead helped build a broad coalition whose influence extended from labor mobilization into party politics and local government. That grassroots participation mattered to the character of the democratic transition: it helped make the restoration of democracy a movement toward broader political inclusion, rather than a change of government alone.
