In a post-pandemic era, managers and leaders have a role to enable the changes needed to make workplaces happier and more productive. This paper aims to analyse the role of neuroleadership in the application of happiness management. Two research questions are proposed: what do we know about neuroleadership? and what role can neuroleadership play in happiness management? A mixed methodology is applied. A bibliometric technique is used to identify the main topics studied in neuroleadership. An in-depth analysis and logical reasoning are applied to propose a neuroleadership research roadmap and to present some research pathways for neuroleadership for happiness management. A neuroleadership research roadmap is proposed, considering the approaches, practices/actions, and purposes. It is observed that the consideration of the management of emotions and cognitive processes in the work environment is attracting interest to develop a leadership focused on making better workplaces. A new line of action focused on the management of happiness is emerging. In addition, neuroleadership is presented as a new way of understanding management. Their combined application can mark a before and after in business management, and for that, a proposal of future research lines and questions is developed. This paper presents four future research pathways—perspectives, reasons, adoption and implementation, and results—for studying neuroleadership for happiness management.
