This article encourages critical discussion about the economic and social consequences of the war in Ukraine. This war has global effects in various dimensions of social life: energy policy, the environmental dimension, the economic sphere, and also the political atmosphere. In each of these dimensions, it poses a threat to sustainable development and the interests of the labour class in Europe. It attempts to change the balance of power in global geopolitics and also proves to be a useful cover for attempts to change the model of relations between employees and the state and business in many European countries. Due to the conflict in Ukraine and the ensuing calls for increased efforts to ‘ensure security’, Europe has turned towards a war economy in which the interests of the arms industry are more important than the interests of the working classes. The war in Ukraine has proved to be an excellent justification for governments to lower social standards and get rid of the remnants of the welfare state. From this perspective, the atmosphere of the New Cold War becomes a challenge for the labour movement, the global left and all progressive social circles.

Based on the material obtained from focus group interviews conducted during the COVID-19 pandemic, the article analyses the mechanisms used by employers towards employees, as well as the adaptation strategies applied by those in precarious employment in Poland. The authors’ considerations refer to anti-worker changes introduced under the pretext of the pandemic in the capitalist labour market: layoffs and cuts in wages, manifestations of discrimination against precarious workers and the potential attitudes of employee self-defence. The authors conclude that it is almost certain that under the conditions of post-pandemic capitalism, the number of the precariat will grow and the neoliberal system will want to retain as many of the anti-worker solutions introduced in the shadow of the pandemic as possible.

Les travailleurs bénéficient de performances différentes sur le marché du travail en fonction de leur âge : le taux d'emploi exhibe une trajectoire en cloche en fonction de l'âge, tandis que le taux de chômage est continuellement décroissant. Au cours des dernières décennies, le taux de chômage a augmenté pour toutes les catégories d'âge, mais essentiellement pour les plus jeunes, tandis que les taux d'emploi et de participation ont essentiellement diminué pour les plus jeunes et les plus âgés. Nous construisons dans cet article un modèle d'appariement à la Pissarides (1990) apte à rendre compte de ces phénomènes.
