Ollman is also the creator of Class Struggle, a board game based around his Marxist beliefs, and from 1978-1983 was president of Class Struggle, Inc., the company that initially produced and marketed the game. The game was later released by a major board game company, Avalon Hill. It received publicity due to its unusual and controversial theme[1].

In 1978, after having his offer of chairmanship of the Government Department at the University of Maryland College Park rescinded, Ollman sued columnists Robert Novak and Rowland Evans, alleging that a column they authored had libeled him, resulting in the rescinding of his offer. The column had characterized his teaching style as indoctrination, including an anonymous quote from another professor saying "Ollman has no status within the profession, but is a pure and simple activist." Ollman's suit was defeated in the D.C. Circuit Court, which held that Novak and Evans' column was protected speech. Ollman v. Evans - AltLaw

In 2001, he won the first Charles McCoy Life Achievement Award from the New Political Science section of the American Political Science Association.

Ollman appeared on "Hannity & Colmes" to face the accusation that as Sean Hannity's professor in the 1980s, he had given him a lower grade for being a conservative and a supporter of Ronald Reagan. Ollman pointed out that he has been a Professor of Political Science at New York University for 40 years, and claimed that had he discriminated against Conservative students he 'would not have lasted long.' Ollman gave a detailed account of his teaching and his explanation of why his non-Marxist students "do at least as well as the rest of the class," in a letter to the editor in the Washington Post 1978.
