What is focused on in the undertaken study are teachers from schools educating in the Polish language in the Czech Republic. The author refers to the studies conducted in 2014–2016 and in 2017 among teachers from schools for the Polish national minority located in Zaolzie. These schools effectively compete with schools for the Czech majority. Among other things, they have survived owing to teachers and their decisive strategies, which involve not only strictly competitive but also various forms of collaborative behaviour.
