This article examines growth in triangular employment and related staffing services. A review of competing understandings of triangular employment growth through the lens of three alternative theoretical paradigms (neoclassical, institutionalist, and critical) illuminates the space for the notion of triangular employment growth as problematic and reinforces the theoretical importance of the relationship between triangular employment growth and labour law. To this end, the concept of a 'regulatory differential' - a differential effect of regulation that occurs as between triangular and direct employment forms - is developed; a taxonomy of various forms, these take in any given jurisdiction is provided; and the relationship between underlying regulatory differentials and employer status rules is discussed.
