Players' union accuses NBA of unfair practices

Claiming the National Basketball Association's use of locker room cameras is an illegal change in working conditions, the league's players filed an unfair labour practice charge with the National Labour Relations Board.

The union also wants to stop the NBA from using boom microphones in team huddles during timeouts.

"The NBA cannot impose these changes without the union's consent," union lawyer Robert Lanza said Monday. "While players certainly want to enhance the game experience for every fan, these types of changes can only be brought about through collective bargaining. We must have a meaningful dialogue in order to strike the appropriate balance between access and intrusion."

NBA coaches earlier complained about the league's attempt to put mikes on them during some national broadcasts. The boom mikes during huddles were part of a compromise with the coaches.
