--- - |2 Drawing on the work of Max Weber, this article considers the utility of an approach to the study of labour law, which it calls the economic sociology of labour law (ESLL). It identifies the contract for work as the key legal institution in the field, and the primary focus of scholarly analysis. Characterizing the act of contracting for work as an example of what Weber called economic social action oriented to the legal order, it proposes that Weber's notion of the labour constitution be used to map the context within which contracting for work takes place. And it argues that, in comparison to traditional socio‐legal approaches, ESLL has the significant advantage of allowing for account to be taken of the individual and commercial, as well as the social and legal, elements of contracting for work. - 'Journal of Law and Society, Volume 46, Issue 3, Page 396-422, September 2019.
