This interim report presents the findings from an online questionnaire of 806 teachers in England. The data gathered here constitute the first phase of my PhD data collection. It explores teachers' working conditions in the state and independent schools sector in England. Specifically, it examines: teachers' working hours; the constitution of teachers' workload; accountability, and the sources and levels of teacher stress in relation to job satisfaction in a sample of teachers from each sector. The findings suggest that while the sampled teachers work similar hours in both sectors, there are significant differences in stress and job satisfaction with independent teachers reporting far higher levels of job satisfaction, and much lower levels of stress. Teachers' experiences of accountability measures also vary according to sector. The next phase of the project aims to further investigate the trends identified here, and identify the conditions that are optimal for teacher job satisfaction and by extension - retention, in both sectors.
