In a context where many post bureaucratic theoretical models and empirical evidences call for taking into account the current hybridization of public work environments, the employment relation between public servants and their organizations demands further investigations. To enable the discovery of new forms and dimensions of commitment, an approach using the foci of commitment is adopted in the present paper. Based on more than 20 explanatory interviews with public employees holding different positions in different contexts, it presents a new typology of commitment foci of public employees and a first discussion of their potential implications for public managers. Commitment in the public sector is characterized by individual, organizational and supra-organizational foci. Following typologies founded, so far, on the bases of commitment, our foci-oriented specification of public commitment contributes with novel insights for public HR specialists and managers, thus enabling a better understanding of workplace attitudes and behaviours; and subsequent adjustment of the policies and practices intended to personnel management.
