Calls to engage more men in the so-called ‘feminised’ primary school environment are omnipresent. Male teachers are expected to bring something new, different and unique to this feminised environment. The aim of this article is to explain the gendered expectations on male teachers in primary schools and describe how male teachers construct their masculinity in relation to these expectations. The article presents the results of an ethnographic research in primary schools in Czechia. The results show that there are at least three most prominent areas—authority, effeminate behaviour, and care—where male teachers search for the appropriate and very narrow concept of masculinity. Male teachers must appear sufficiently masculine, but not too masculine, because they are doing masculinity in a predominantly female environment. The article provides a novel contribution on two levels. Firstly, it examines the balancing of masculinity and conflicting expectations imposed on men in primary education. Second, it shows that despite the diversity of geographical, historical, and geopolitical school contexts, the local expectations about masculinity bear striking similarities.
