Trends in the problem and subject field of labor sociology were identified by referring to the Sociological Studies journal publications for 1974–2023. An array of 351 articles on labor sociology was selected for qualitative and quantitative content analysis. Eleven problematic subject areas of research were identified by the criterion of the leading target of the article’s text. Fourtime frames in Russian society and economic development over the past 50 years have been distinguished to identify the time challenges that vary in content. Each period was provided with a brief description of the content of the research problem and subject areas, as well as interpretations thereof with due consideration of the time challenges. Analysis of the publications permitted to reveal that by the criteria of how frequent and stable the sociologists’ referrals to the selected areas have been, the core, the margins, and the mobile realm may be identified in the Russian sociology of labor. The core is formed by the areas related to the studies of labor attitudes, labor incentives, labor values, employee behavior, and job satisfaction. The areas – whose principal object of study is labor itself, along with its role and significance in both the society and the employees’ values as well as social problems of work at the enterprise – are adjacent to the core. The margins are formed by rare areas of research such as the workers’ capacity to act, manifestations of independence and involvement in the organization’s affairs, problems of the socioeconomic standing of workers and degree of labor protection, labor culture, shortage and reproduction of workers. The mobile realm of labor sociology is composed by the areas treated generally depending on the context of time and the aggravation of particular problem situations (labor organization, labor relations, precarity of labor, etc). We observed adequate coverage of the critical time challenges in publications in all those time frames; however, that coverage was reactive and appeared to lack forward-looking ideas that are ahead of theory and practice.
