Workers in Fairfax County are asking the National Labor Relations Board to change its policies so they can vote to remove union bosses at any time during a contract.

Under NLRB rules, workers cannot vote to oust union representatives until after a contract has expired or after three years have passed, whichever is earlier. Employees at Transdev, a public transport company, who are working at the public bus service Fairfax Connector are seeking a change to the rule with legal help from the National Right to Work Legal Defense Foundation.
