Good management and leadership are key-factors for sustainable development and long-term success in all types of organisations. Although, many organisations are still struggling with quality problems, sick absence and financial difficulties caused by poor top management. Many researchers have reported on relationships between good management and working environment, quality and efficiency. So the question is why god management is not practised to a larger extent? In this paper, management methodologies for sustainable health among employees, customer satisfaction and good bottom line results are explored by studying top leaders in three Swedish successful organisations. General questions dealt with in the paper are: How can managers commit employees to be part of the proactive work with sustainable health? And what methodologies can top managers use to get well-motivated employees, a good working environment, satisfied customers and good financial results? The studied organisations are two manufacturing companies and one hospital. The organisations have received national awards for their excellence in leadership, internal partnership, working environment and efficiency. They all demonstrate good examples of long-term work with sustainable health among employees which has decreased sick absence. Explorative qualitative methods have been used to identify management methodologies in the case organisations. The results confirm a relation between leadership and sustainable health. In all organisations sustainable leadership has been characterised by great humanity, a long-range perspective and a holistic view of management. These management methodologies with concrete examples have been described in the paper. The leadership has led to healthier organizations with more committed and satisfied employees, and the indicated relationships between sustainable leadership, improved health among employees, satisfied co-workers and bottom line results among the case organisations probably demonstrate a significant improvement potential for today's organizations.
