Purpose: The purpose of this paper is to examine individuals' levels of work ethic amongst current and recent university attendees across three countries. This article presents the results of a survey of 537 respondents from the United States of America, Korea and China, thus extending the previous research into work ethic, often conducted from a Western perspective. The comparative study aims to enhance the understanding of cross-cultural and gender differences and similarities whilst probing for the levels of work ethic amongst the respondents. Design/methodology/approach: A comparative research method was adopted because the authors' aim was to probe similarities and differences across three societies. Multiple analysis of variance (ANOVA) and t-tests were utilised to explore gender and country-related differences. Cluster analysis was applied to probe for segments highly similar to each other in the levels of work ethic of the respondents. Findings: The results confirm the hypothesised differences between countries as well as across gender groups, with American females having the highest levels of work ethic, closely followed by Chinese males and females. Three distinct segments -- low, medium and high levels of work ethic -- were found in all three countries, indicating that there are individuals in each of the societies who could benefit from strategies for increasing the individuals' levels of work ethic. Originality/value: Novel gender comparisons of the three country groups revealed American females as having the highest levels of work ethic and Korean females the lowest, whilst the identification of clusters of low, medium and high levels of work ethic provides evidence of the need to increase levels of work ethic to enhance productivity, regardless of the country of origin.
