This contribution focuses on the categories and the epistemic horizon adopted for interpreting the changes of labour, both in historiography and the social sciences after 1989. The review of a wide body of scholarship intends to cast light on the interaction existing between the research topic and its interpretation. The article focuses on how labour changes
have been looked at in the European context, and it includes analyses relating to both the Eastern European and the North American areas, of use in order to better understand the changes and the pervasiveness of certain categories in the post-1989 period. The influence of global studies and global history on post-1989 labour history is also taken into account.
