Are Firms Ready for Workforce Ageing? Evidence From Small‐Medium Sized Firms in Italy

open access: yesLABOUR, EarlyView.
ABSTRACT We investigate age‐related human resource management (AR‐HRM) practices within SME in Italy. Using firm‐level survey data with information on age‐related attitudes and practices, we analyze the determinants of age management and outplacement practices, along with the role of collective bargaining.
