The object of the current Thematic Issue is not to focus on the individuals (the cross-border commuters) but on the organization of the cross-border labor markets. We move from a micro perspective to a macro perspective in order to underline the diversity of the cross-border labor markets (at the French borders, for example) and shed light on the many aspects that impact cross-border supply or demand. Trying to understand the whole system that goes beyond the cross-border flows, the question we address in this thematic issue is about the organization of the labor markets: is the system organized in a cross-border way? Or do the borders still prevent a genuinely integrated cross-border labor market?
In the course of the COVID-19 pandemic, borders have become relevant (again) in political action and in people's everyday lives within a very short time. This was especially true for the inhabitants of border regions, whose cross-border life worlds were suddenly irritated by closed borders and police controls. However, the COVID-19 pandemic also led to an increased evidence of social, cultural, economic, health and mobility boundaries beyond national borders, which raised pressing questions about social inequalities. The authors shed light on these dynamics from the perspective of territorial borders, social boundaries and (dis)continuities in border regions through a variety of thematic and spatial approaches. The critical observations and scientific comments were made during the lockdown in April and May 2020 and provide insights into the events during the global pandemic.
