Djalma Bom is a former Brazilian politician and a founding member of the country's Workers' Party, the party of former president Luís Inácio Lula da Silva.
In 1978 Djalma joined the board of the Steel Worker's Union with Luis Inácio Lula da Silva then on the road to become an important leader. Together they organized major activities including strikes. These strikes were not seen under favourable light by the military government and the Union main board was jailed for a month in May 1980.
In early 1982 a group of academics, union leaders such as Lula and Djalma, and intellectuals founded the Workers' Party, a left-wing party created during the military dictatorship and, in the upcoming elections in November, Djalma was elected to a seat in Congress in Brasilia. In 1988, he became the Vice-Mayor of São Bernardo do Campo.
He was re-elected in 1994 to the Legislative Assembly in São Paulo, and retired after this tenure.
