<p>Positive relationships at work have been found to be beneficial, leading to outcomes such as improved well-being and work performance. One reason positive relationships are believed to be beneficial at work is that they are a source of positive relational energy—an increased level of psychological resourcefulness generated through interactions with others that leads to an increased capacity to do work. Leaders have been identified as especially important for generating positive relational energy. For example, Cameron (2021) has argued that the most successful leaders are typically positively energizing leaders who, through virtuous behaviors characteristic of positive leadership, energize followers, which leads to better work performance. The aim of this systematic review is to examine the empirical evidence to determine whether positive leadership generates positive relational energy among followers, leading to their improved work performance.</p>
