Frequent Job Changes Can Signal Poor Work Attitude and Reduce Employability

We study whether employment history can provide information about a worker’s non-cognitive skills - in particular, about “work attitude,” or the ability to work well and cooperatively with others. We conjecture that, holding all else equal, a worker’s frequent job changes can indicate poorer work attitude, and that this information is transmitted in labor markets through employment histories. We provide support for this hypothesis across three studies that employ complementary lab, field, and survey experiments. First, a laboratory labor market, in which the only valuable characteristic of workers is their reliability in cooperating with an employer’s effort requests, demonstrates that prior employment information allows employers to screen for such reliability and allows high-reliability workers to obtain better employment outcomes. Second, we conduct a field experiment that varies the frequency of job changes in fictitious job applicants’ resumes. Those applicants with fewer job changes receive substantially more callbacks from prospective employers. Finally, a survey experiment with human resource professionals confirms that the resume manipulations in the field study create different perceptions of work attitude and that these account for the callback differences. Our work highlights the potential importance of job history as a signal of worker characteristics, and points to a cost for workers of frequent job changes.
