Flexibility stigma, the devaluation of workers who seek or are presumed to need flexible work arrangements, fosters a mismatch between workplace demands and the needs of professionals. The authors survey “ideal workers”-science, technology, engineering, and math faculty at a top research university-to determine the consequences of working in an environment with flexibility stigma. Those who report this stigma have lower intentions to persist, worse work-life balance, and lower job satisfaction. These consequences are net of gender and parenthood, suggesting that flexibility stigma fosters a problematic environment for many faculty, even those not personally at risk of stigmatization.
