Hybrid work models have rapidly become the most common work arrangement for many knowledge workers, affording them with improved work–life balance and greater levels of job satisfaction, but little research has been conducted to identify the different hybrid work models that are emerging, and the appropriate supports needed to drive sustainable improvement. This paper utilises primary data from a series of semi-structured interviews with senior Australian human resource (HR) managers, to identify a range of different approaches to hybrid work design, applying the Conservation of Resources (COR) theory. Analyses of these findings have resulted in five key contributions: one being the identification of the most popular current hybrid work arrangements; the second being the key supporting pillars that are required to support successful hybrid work; the third identifies the infrastructure required to support these pillars; the fourth being a theoretic contribution that extends the existing academic literature in this field; and with the final contribution being an interpretation of the findings via COR theory. These contributions have significant implications for both scholars and human resource professionals, as organisations and academics strive to learn from the recent period of turbulence and develop sustainable improvements in performance and working conditions (SDG8), with improved support for employee health and wellbeing (SDG3), and gender equality (SDG5).
