The need for schools to support children and young people's mental and emotional health is increasingly emphasised in policy initiatives, yet the role of teachers in this has been under explored. This paper reports findings from qualitative, semi-structured interviews with 14 school staff at eight secondary schools in England, examining emotional health and well-being (EHWB) activities in which they were involved. Three emergent themes are discussed: (1) a strongly held belief that teaching and EHWB are inevitably linked; (2) a perception that many colleagues outside the study sample are reluctant to engage in EHWB work; and (3) a concern that teachers' own emotional health needs are neglected, leaving them unable or unwilling to consider those of pupils. The findings endorse whole-school approaches to emotional health, with a focus on teachers' training and support needs and clearer aims, including consideration of how such work fits with the broader goals of schools.
