This paper examines communication processes between state institutions and migrants under the conditions of the COVID-19 pandemic. It aims to determine where migrants obtain their information on specific legal regulations and restrictions on rules of conduct in the public space and professional environment. This issue is examined through the example of Ukrainian labour immigration in Poland. Referring to the results of our survey research, it is established that in a crisis, when the importance of information in the public sphere increases and, at the same time, direct social contacts are restricted, the special role of the employer is revealed. The employer is perceived not only as an entity offering work, but also as an important channel of information about state policy, regulations and rules of conduct applicable in a crisis. These findings are an indication, on the one hand, for state institutions to take this role of employers into account in migration policy and,
on the other hand, for employers themselves to be aware of their social role towards migrants and play it responsibly. We believe that the study, conducted in the first two months of the pandemic, has become very timely with the outbreak of the Ukrainian–Russian war.
