A meeting of union representatives Tuesday voted unanimously to establish a code of conduct for union members and to create an ethics board.
A task force of approximately 20 Teamsters will oversee the development of a code of conduct, with a first draft expected by mid-April.
The union also plans to do a study of the union's efforts to sever ties with organized crime.
"We want to move ahead and do this study and verify the fact we are corruption free," said Hoffa, who won the Teamsters' presidency on pledges to end the federal oversight. The union agreed to the oversight in 1989 to avoid racketeering charges. The federal monitoring has cost the Teamsters $83 million, Hoffa says.
According to the Associated Press, government officials have met with the Teamsters, but gave no indication the Justice Department is willing to drop its oversight of the union.
