Since March 2020, the COVID-19 pandemic has changed the working life of the entire working population in the Netherlands. TNO started a cohort study (NWCS-COVID-19) just before the pandemic, and follows this group of employees until 2021. This group completed the regular NWCS in November 2019 and received follow-up questionnaires in June 2020, November 2020, March 2021 and at the end of 2021.

This research by TNO provides insight into the consequences of the COVID-19 pandemic on working conditions, health and future prospects. In addition, it is also possible to highlight vulnerable groups.

Which target groups can we distinguish?

Because working life has changed for almost everyone, but not always in the same way, there are three target groups that we can distinguish, namely:

Working from location
Individuals who mainly work from location (of their employer or customer)
Working from home
Individuals who mainly work from home
Less or no work
Individuals who have (almost) no work or work-related activities


Who participated?

The fieldwork for the first follow-up measurement of the NWCS-COVID-19 was carried out between the end of June and the end of July 2020, 3 months after the start of the governmental measures and before the resurgence of COVID-19 in August 2020. The fieldwork for the second measurement was carried out in November 2020, during the second wave, at a time when infections continued to rise and a partial lockdown had been introduced. The fieldwork for the third measurement was carried out in March 2021, during the third wave when measures were further tightened.

Information is available for a total of 10,616 participants from both 2019 and the first measurement of 2020. Information from 2019 and the second measurement of 2020 is available for 9,829 participants. For 8,911 participants, information is available from both 2019 and the third measurement of 2021. Lastly, for 8.099 participants, information from both 2019 and the fourth measurement at the end of 2021 is available.

In total, 3,928 participants took part in all five measurements.
