This article subjects the work ethic that is discussed from the Weberian perspective, which attributes positive meanings to it in T & uuml;rkiye, to a Marxist critique, and it aims to show how work is moralised for the working class during the different periods. The paper claims that this moralisation practice aligns the working class with the interests of the ruling class. In parallel with this aim and claim, document analysis is employed, which is a dimension of the qualitative research method. To demonstrate transformations in work ethic, a variety of sources have been used, including changes in labour policies, regulations related to working life, studies addressing moral transformations, and career planning course curricula that have become widespread in universities in recent years. Research and analysis reveal that the main themes are the Ahi work ethic based on contented teachings; working for the nation and homeland in line with modernisation and Westernisation; the sense of belonging to work created by the welfare state model; and the narratives of entrepreneurship, flexibility, and being one's own boss, which are characteristic of the neoliberal era. In this sense, the paper invites scholars to evaluate work ethic from a different perspective.
