In keeping with repeated calls to investigate high early career turnover within the teaching profession, the present study investigated the hypothesis that a significant positive association between burnout and turnover intention would be observed in teachers at the beginning of their careers. A sample of 112 Australian teachers working in their first or second academic year was surveyed in 2004. Respondents were administered the Maslach Burnout Inventory (MBI: Maslach, Jackson & Leiter 1996) and asked about serious intentions to leave their job and/or profession. Meaningful and significant associations between serious intentions to leave and all three MBI subscales were found. The findings suggest a realistic and straightforward explanation for the alarmingly high early career attrition rates that are now commonly reported for the teaching profession in a number of countries.
