BACKGROUND: Despite an increase in work-life balance literature, the development of successful support to help employees manage their work -life balance is slow. Moreover, there are few interventions with a comprehensive approach to workplace health promotion focusing on work-life balance. OBJECTIVE: This paper aims to present the development and building blocks of a holistic interdisciplinary health-promoting program, the BELE program, to enhance female employees working in human service organizations health and well-being with a focus on work-life balance. METHODS: The planning and development of the program was done through an intervention mapping and research circles methodology. RESULTS: The planning- and development process of the program resulted in a theoretical framework, and a program structure with a program content. The intervention program was named "The Balance in Everyday Life Empowerment program" (BELE program). CONCLUSIONS: The BELE program adds to the existing body of work-life balance knowledge, so far often based on a conflict approach. Interventions focusing on a comprehensive approach to health and work-life balance with a salutogenic approach are rare. Furthermore, the integration with occupational therapy and health promotion in a workplace health promotion framework is innovative. In a previous study, the BELE program has shown that it enhances women's well-being and balance in their everyday life. [ABSTRACT FROM AUTHOR]
