Hasbro (HAS) subsidiary Wizards of the Coast's workers are seeking management's voluntary recognition of their union, the Communications Workers of America labor union said Monday.

The workers sent a letter to management earlier Monday outlining issues they target to address as a union and gave management until the end of the week to recognize the union, according to a statement.

The workers, who are involved in designing the digital game Magic: The Gathering Arena, also filed an election petition with the National Labor Relations Board, the CWA said.

Hasbro and Wizards of the Coast did not immediately reply to a request for comment from MT Newswires.
