Umpires cited unilateral changes made to the strike zone and changes to the job evaluation process among the reasons the National Labor Relations Board should seek an injunction to keep 22 umpires from being let go next week.

In a 44-page brief submitted to the NLRB, the Major League Umpires' Association said the union's power and status had been undermined by the decision of the American and National leagues to accept the resignations of 22 umpires while letting 35 other umps withdraw theirs.

Owners responded through their new outside lawyer, Howard Ganz of Proskauer Rose LLP, who has played a prominent role for the NBA owners in their labor struggles.

Ganz, according to a management official speaking on the condition he not be identified, told the NLRB that most of the matters raised by the union should be decided by an arbitrator and that many of the union's accusations are unfounded.

If the NLRB issues a complaint, it could ask a federal judge to issue an injunction to keep the 22 umps on the job.
