Working Around the Clock: Temporal Distance, Intrafirm Communication, and Time Shifting of the Employee Workday

This paper examines the effects of temporal distance generated by time zone separation on communication in geographically distributed organizations. We build on prior research, which highlights time zone separation as a significant challenge, but argue that employees may time shift—move work-related communication to outside of regular business hours—to counteract temporal distance. We propose a theory in which employees’ tendency to time shift depends on the demands of their tasks and collaborative relationships and individuals’ ability to supply work outside of regular business hours. Analyzing communication-level data from 12,038 employees of a large multinational firm and using cities’ shifts to/from daylight saving time for identification, we find that temporal distance leads to sizable but smaller than expected reductions in volumes of rich, synchronous communication between employees. Consistent with our arguments, we find that increased temporal distance significantly increases time shifting of work-related communication, especially among workers whose jobs are non-routine and interactions in strong collaborative relationships. We further document that female employees and employees based in countries with stricter legal work hour limits engage in significantly less time-shifted communication. Our study improves understanding of a ubiquitous source of collaboration friction. It also sheds light on a potential source of inequities in workplace outcomes stemming from differences in individuals’ ability to work outside of regular business hours.
