Kalogridis became involved as a peacemaker in the 2007–2008 Writers Guild of America strike, working with writers and producers to reach a solution. "The New York Times" reported her involvement, "Ms. Kalogridis and her friends... had become a pipeline to the guild members holding out for sizable gains, whose support would be needed if any deal was to be reached." She is also the founder of the pro-union website Hollywood United.
