This paper investigates the phenomenon of mothers' emotional labour in relation to children's transfer from first- to second-level schooling: a time that has been shown to pose significant challenges for students and their families. It seeks to break the silence that surrounds the recognition and production of emotional labour in general, and specifically in relation to education. Drawing on 25 case studies, this research explores in-depth both the extent and nature of emotional work in mothers' daily practices. Against that backdrop it identifies the specific emotional work performed at school transfer. It examines mothers' common experiences in shouldering emotional education work and finds that mothers are key education workers. This research suggests that mothers' lives are shaped by caring labour including education work: labours that are largely unseen but that are inalienable, and demanding on their time and energies.
