On Monday, the staff was informed about the change in a message that CNBC has taken part of.
CEO Dara Khosrowshahi writes that the change will improve the company's ability, although remote work may have some advantages.
"Being in the office promotes collaboration, increases creativity and boosts tempo", writes Khosrowshahi.
Several companies in the American tech industry have started requiring their staff to work in the office. Last week, Google informed its employees that they must work on site three days a week, otherwise they will lose their job.
