Abstract
Purpose: The literature on HR metrics does not address the political issues that surround the definition and interpretation of these metrics. However, the need for agreement about HR metrics between different stakeholders is underlined by the framework of the sociology of quantification. This research aims to complement the literature on HR metrics by studying the process of defining and interpreting appropriate HR metrics, focusing on the example of the gender pay gap.Design/methodology/approach: A case study with interviews and participant observation is conducted on a French company.Findings: The results show that HR metrics are essential to prove the existence of inequalities. However, there are disagreements between management, unions and gender equality referents concerning appropriate HR metrics and their use.Originality/value: Contrary to the literature on the subject, which remains predominantly positivist and normative, this article sheds light on the political issues surrounding the definition and use of HR metrics and shows the importance of involving a range of actors (managers, unions and employees) in the entire process.
