Background: Leadership has been widely studied over the years due to its importance to organizations. The leader must be able to direct their team to reach the objectives and goals established in the organization, creating a work environment capable of providing this. Value-oriented leaders, teams, organizations, and communities are the most successful when they are able to engage workers in such a way that there are gains in retention rates and reduced absenteeism. Quality of Work Life is something that goes beyond labour laws. It is a dynamic that involves physical, technological, social, and psychological factors, which change and influence the organizational climate, reflecting on the worker's well-being and, consequently, on their productive capacity. Objective: To analyse the relationship between leadership styles, personal values of nursing leaders and the Quality of Work Life of nurses who attend the Graduate Program in Nursing Management (PPGEn). Methods: This is a quantitative, cross-sectional study. Data were collected using the standardized instrument Quality of Working Life Questionnaire (QWLQ-bref), and an exploratory-descriptive analysis was performed. Results: Of the 123 nurses interviewed, 64.22% rated the Quality of Work Life as satisfactory and 31.7% as very satisfactory. Through these data, the relationship between the task leadership style and professional satisfaction in the nurse's quality of life was perceived. Conclusion: The results do not point to a relationship between the managerial style of the nurse leader and the perception of Quality of Work Life. However, it is noteworthy that the Quality of Work Life describes values that go beyond the human. Conclusion: The results of this study did not indicate a correlation between leadership styles, personal values and the perception of Quality of Work Life, however, conclusions can be made from the highest and lowest scores presented. Everyone in a leadership role should be aware of the values they hold, their strengths, and the areas they can improve as they grow as a leader. The importance of a positive organizational climate so that the established goals are achieved is clear, and, in this sense, valuing the human factor will make the achievement of goals more feasible.
