Early Americans were credited with holding the Protestant work ethic, a set of work-related beliefs involving the traits of industriousness, individualism, ascetism, community involvement, and an overall valuing of work as the most worthwhile way to spend one's time. The American work ethic today is not the same as it was in early America. In order to examine whether the American work ethic today is undergoing a significant change, it is important to examine the major characteristics of individuals who endorse the Protestant work ethic. This study was conducted to investigate the relationships between the Protestant work ethic and some demographic variables in a sample of 689 subjects in the middle Tennessee area. Subjects completed a 25-page questionnaire which included the Mirels-Garrett Protestant Work Ethic Scale and items measuring selected demographic variables. The results revealed that Protestant work ethic endorsement was positively related to Republican Party identification and negatively related to age, educational level, employment status, annual income level, and marital status. A similar pattern of results was also found using one-way analyses of variance. (Author/NB)
