This paper provides a historical analysis of workplace wellbeing, showing that modern wellbeing initiatives are not new but part of a long evolution of managing employee health. It identifies three key phases, paternalism, human relations, and managed autonomy, each shaping how employees are expected to think, behave, and care for themselves. Across all periods, wellbeing is framed as a way to create “fit for work” employees while responding to wider social concerns. The study challenges the idea that workplace wellbeing is purely beneficial, highlighting how it has consistently been used as a tool for influencing behaviour and reinforcing organisational goals.
