Guided by neoliberalism and post-colonialism, this article takes the case of global citizenship education (GCE) in South Korea to explore social studies teachers' experiences and their everyday voices in teaching GCE. The findings demonstrated a number of barriers that teachers confront and the entrenched ideologies behind these hurdles, which contributes to the marginalisation of GCE. By drawing scholarly and policy implications that consider the complicated global/local nexus of GCE within dominant Eurocentric and neoliberal discourses, the study adds to existing research on teachers' GCE practices from different societies and expands upon the critique of Western-centric, neoliberal perspectives embedded in GCE.
