In the battle over Children’s Place, no one is playing nice.

Chairman Norman Matthews told shareholders in a letter this week that dissident investors had a “questionable track record” and were behaving erratically. He took specific aim at Jonathan Duskin, chief executive of Macellum Advisors, describing his professional affiliations as “abject failures.”

Macellum and Barington Capital Group have a 2.1 percent stake in the retailer and are asking shareholders to oust Matthews and another director and elect their nominees.

The investors blasted Matthews’ “track record” as a director on the boards of six companies, including Loehmann’s and Levitz, that filed for bankruptcy.

This week, proxy adviser Glass, Lewis & Co. sided with the dissidents ahead of the May 22 annual meeting.

“We believe this contest provides a compelling opportunity for shareholders to hold the incumbent board and in particular, Mr. Matthews, accountable for poor performance,” Glass Lewis said.

Children’s Place said the report was “based on a deeply flawed analysis.”
