hard hat. Hard hat used to be a designation for a man who wore a derby hat, especially Eastern bankers and businessmen during the 1880s. A century later, in the late 1960s, it came to mean a construction worker, because of the metal or plastic safety helmets such workers wear. Because these hard hats of- ten clashed with antiwar demonstrators during the early 1970s and supported the war in Vietnam, the term hard hat also came to mean a political conservative. |
