Workers at Media Matters for America, the nonprofit liberal media watchdog, will definitely hold a vote on whether to form a union, according a statement posted online by Service Employees International Union Local 500. The announcement marks a big win for the union, which had earlier faced stiff opposition from the nonprofit’s management to collective bargaining.

The announcement was posted on Local 500’s website Thursday and attributed to the Media Matters Organizing Committee, a workers group. It did not state exactly when the election would be held other than to say it would be “soon.”
