Although the term work–family/life balance is widely employed, an agreed definition of this term has proved elusive. Instead, an array of definitions and measures populate the literature. The variety of work–life definitions and measures provide limited value for both the theoretical advancement of the construct and for practical human resource (HR) interventions. In this article, we review six conceptualisations of work–life balance found in the literature: (1) multiple roles; (2) equity across multiple roles; (3) satisfaction between multiple roles; (4) fulfilment of role salience between multiple roles; (5) a relationship between conflict and facilitation; and (6) perceived control between multiple roles. Based on our review of this research we identify the two primary features of the work–life balance definitions and propose a new definition of this construct.

Professor Steven Poelmans is a leading international expert on the frontiers of work–family research contributing to theoretical and practice advancements. He is the Academic Director of the International Centre of Work and Family (ICWF) at IESE Business School in Barcelona, Spain, which has worked for more than a decade with numerous organisations in Spain, Latin-America, and various countries around the globe to create a family-responsible environment. In this conversation, Steven Poelmans responds to questions from Thomas Kalliath and Paula Brough (Guest Editors) on a range of theoretical and practice issues currently facing the field including measurement of work–life balance, work–life balance theory, engagement with industry, the role of organisational culture and strategic management in influencing work–life balance.
