This research investigates factors that impact the use of electronic human resource management (e-HRM) systems at SEAT, a car manufacturing firm of the Volkswagen Group. This study builds on the unified theory of acceptance and use of technology to analyze the relationships between user acceptance of e-HRM systems and its antecedent factors, namely performance expectations, ease of use, social influence, and facilitating conditions. The empirical study takes advantage of how employees at SEAT use a new e-HRM system implemented by the human resource department in the context of a business digitization strategy. One hundred and sixty-nine employees at SEAT were conveniently sampled to bring light to the most influential predictors of e-HRM user acceptance. Hierarchical multiple regression shows that performance expectations and ease of use have positive relationships towards acceptance of e-HRM technologies. In addition, this research provides some practical implications to guide HR professionals on the implementation of e-HRM systems.
