In the aftermath of the COVID-19 pandemic and amid the present reconfiguring of corporate purpose, there is an opportunity to realign actions focused on prolonging working lives. We put forward a transformative agenda concerned with workforce ageing that aligns with contemporary expectations regarding sustainability, inequality, and emerging conceptualisations of management. In this article, the new concept of Common Good human resource management (HRM) is utilised as a potential means of encouraging business responses focused on grand challenges such as population ageing. We suggest how these principles might be applied to the issue of managing age in workplaces, to recast debate about issues of age and work, to be used as an advocacy tool encouraging employer engagement, while providing a framework that might direct organisational leadership.
