We introduce a themed collection of articles examining how the public sector has responded to, and been impacted by, the COVID-19 crisis. Although the pandemic has affected the roles, functions, economies, governance and structures of public sectors, this themed collection focuses on public sector employment relations. Authors examine significant areas which have been subject to accelerated change stemming from the pandemic. Building on decades of public sector reform, these changes impact public sector enterprise bargaining, terms and conditions of employment, working arrangements and practices, and the relationship between public servants and their employer. The articles in this collection provide important insights into the longer-term influences of the COVID-19 pandemic for public sector workforces. The collection also raises questions around whether the positive lessons from this crisis can be sustained to help manage serious crises in the future, or whether the public sector will slip back into a state of unpreparedness.
