I study the costs of interacting with automation technologies in a task-switching environment. In the experiment, subjects choose between a manual option without task-switching and an automated option with task-switching but higher expected earnings. By exogenously manipulating the automatability of the production process, I identify task-switching costs and decompose them into objective productivity costs and subjective psychological costs. Objective costs contribute little to the overall task-switching costs, while subjective costs play the dominant role. There is considerable heterogeneity in subjective costs, with a substantial share of subjects finding task switching beneficial. The results suggest that automated workflows, while boosting productivity, can impose subtle yet tangible costs on workers, although the experience of these costs will be highly unequal.
