Building off Nathaniel Grow's excellent post from yesterday, various sources report that the NHL players have indeed begun voting to allow their union's executive board to file a formal "disclaimer of interest." This disclaimer of interest would end the union's collective bargaining relationship with the NHL -- making it easier for the players to bring an antitrust claim against the league.
If the NHL players vote favorably, it would mark the fourth time in sports-labor history that a players union has gone this route. The first was on November 3, 1989, when the NFLPA voted to renounce collective bargaining and then filed a labor organization termination notice with the U.S. Department of Labor -- leading to the Powell III, McNeil and White lawsuits. The second and third involved the NFLPA and NBPA -- both in 2011.
For more on past use of this strategy and its outcomes, see my article from this morning on Forbes SportsMoney.
