Surprisingly, the literature does not contain one clear definition or measure of work–life balance that has demonstrated acceptable construct validity on the criteria discussed above. Instead, an array of definitions and measures populate the literature. We suggest that this 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. We provide here a brief review of the more common work–life balance definitions, with the intention of highlighting this variety and stimulating discussions towards a consensus.
