Some events in world history have affected global social and economic processes significantly. One such event was undoubtedly the commencement of the COVID-19 pandemic. Being in lockdown with access to the Internet and tools that enable remote working enabled and, in fact, forced a change in the form of work to be fully remote, which was previously difficult to imagine in many organisations. As part of this study of the above phenomenon, research was conducted on employees of the IT sector in Poland. An analysis of survey data showed the impact of individual work modes on productivity ratings and collaboration with other team members; additionally, the findings may indicate behaviour changes among employees caused by employer enforcement of changes in work mode, and the importance of the work mode for employees when taking up employment. Although the end of the COVID-19 pandemic has been officially announced in Poland, its impact on the labour market has been significant. The present study shows the popularisation of remote working and a change in attitude towards this form of performing professional duties.
