Should job seekers explain employment gaps? Experimental evidence from Australian employers
(Co-authored with Todd Morris and Christine Ablaza)
Workers with long employment gaps often face discrimination from employers and are commonly advised to explain these gaps. Yet such explanations may be ineffective or even backfire. Using a vignette experiment with over 1,500 Australian employers, we provide the first evidence on how gap duration and reasons jointly shape employer perceptions. When no reason is provided, we find that candidates with long gaps (24–26 months) are rated 0.4 standard deviations lower than those with short gaps (2–4 months) on the interview and hiring scale and are perceived as lacking motivation, mental fitness, and soft skills. Providing a reason for the gap eliminates three-quarters of this penalty, consistent with Bayesian updating. However, we find significant heterogeneity across reasons. Explanations like caregiving or firm shutdown significantly improve employers’ intentions to interview and hire candidates with long gaps. Disclosing a physical injury harms only short-gap candidates, while a mental health condition harms both, revealing strong mental health stigma. These results suggest low-cost, scalable interventions: employment services can provide tailored guidance on when disclosing the reason improves hiring prospects.
What do employers want? Examining the mismatch of labour demand and supply through a study of employment services
(With Ria Thornton, Christine Ablaza, Rose-Marie Stambe, Todd Morris, Greg Marston and Workways Australia)
This project examines employer perspectives on active labour market programs delivered by employment service providers, investigating the disconnect between job seeker expectations and employer experiences in recruitment through employment services. Using a mixed-methods approach, the research combined in-depth qualitative interviews with both employers and job seekers alongside a vignette experiment involving hiring managers across Australia. The findings provide comprehensive evidence to improve employment service provider practices and inform evidence-based labour market policies.
