We examine contingent employment arrangements, assuming that agents perceive them as exceptional opportunities to signal their capabilities to the labor market. We study a multitask career-concerns model in which employment contingency shifts effort toward highly visible tasks at the expense of less visible ones. Exploiting a distinct setting of contingent employment in professional soccer, we test this effort-visibility hypothesis via entropy balancing. Consistent with the model, we observe that agents reallocate effort toward more visible actions while reducing effort in more subtle actions.
