From Yahoo! Sports:
"NEW YORK (AP)—The NBA players’ association filed an unfair labor charge against the league Tuesday with the National Labor Relations Board, a move it hopes could block a lockout it feels owners want.
The players union says the NBA hasn’t bargained in good faith, has made financial demands without offering concessions to the players, and has bypassed the union to deal directly with players.
The charge filed with Region 2 of the NLRB seeks “an injunction against the NBA’s unlawful bargaining practices and its unlawful lockout threat.”"
