Graph of the rise in productivity after the shift to remote work at a call centre in Turkiye showing more calls processed per hour. The Covid-19 pandemic sparked a large and lasting shift to remote work. This column draws on detailed administrative data from a major call centre in Türkiye to show that a permanent shift to fully remote work can expand recruitment and raise productivity without compromising service quality. The transition increased the share of women, including married women, as well as employees from rural areas and smaller towns. Productivity gains were driven by quieter home environments and more efficient communication. But the benefits of in-person onboarding persist, even in a permanently remote work model.
