Work scheduling research typically prescribes task sequences implemented by managers. Yet employees often have discretion to deviate from their prescribed sequence. Using data 2.4 million radiological diagnoses, we find that doctors prioritize similar tasks (batching) and those they expect complete faster (shortest expected processing time). Moreover, exercise more as accumulate experience. Exploiting random assignment of doctors’ queues, instrumental variable models reveal these deviations...
Accuracy and consistency are critical for inspections to be an effective, fair, useful tool assessing risks, quality, suppliers—and making decisions based on those assessments. We examine how inspector schedules could introduce bias that erodes inspection quality by altering stringency. Our analysis of thousands food-safety reveals inspectors affected the outcomes at their prior-inspected establishment (outcome effects), citing more violations after they inspect establishments exhibited...

Struggling to attract talent, companies are scrambling offer schedule flexibility. Analyzing data from more than 44 million job-application decisions across occupations and a major job-search platform, we investigate how offering or requiring worktime flexibility affects worker attraction. Consistent with behavioral organizational theory, find that the value of depends on job type: Offering it increases application likelihood significantly for temporary jobs but much less permanent jobs. And...
