Stress is a widespread feature of work in teaching. Recent accounts of teac
her emotions and cultures of teaching have noted that unsatisfactory social
relationships with adults, e.g. colleagues, headteachers, parents and insp
ectors, elicit hostile emotions from teachers and appear to be a source of
stress in teaching. This article examines why this should be the case. Some
commentators have used labour process theory to argue that the intensifica
tion of work and government policies promoting managerialism in schools are
the roots of the problem. This article uses qualitative data from a study
of primary teacher stress to examine staff relationships in the primary sch
ool. It argues that while intensification of teachers' work is certainly in
volved in eroding positive staff relationships, it is also the changing tru
st relations in high modernity that are shaping the social relations of low
-trust schooling, and impacting negatively on teachers' physical and emotio
nal well-being and their collegial professional relations.
