Many knowledge workers in the manufacturing sector from IT, research and development, sales, finance, customer care and management transitioned to work from home because of COVID-19 (Eurofound, 2020). We investigated how such an abrupt transition affected productivity. Data were collected from 138 white-collar workers using a survey shared on social media. Most of the respondents stated that working from home affected their productivity positively due to fewer interruptions and more efficient meetings. Some employees reported decreased productivity due to problems with the organisational, social and physical working conditions. The work environment should be actively managed when working from home.
