This paper reports the results of an attitudinal survey of resident medical officers (RMOs) to assess their level of job satisfaction. The survey questionnaire consisted of 31 statements or questions concerning RMOs' attitudes towards various aspects of their work. One-third of RMOs employed in New Zealand hospitals were questioned, totalling 524 doctors, and yielding a 74.4% response. Levels of job satisfaction were higher than expected given recent publicity which has stressed dissatisfaction and low morale. The study found that about 66% were satisfied, 20% were neutral and 14% were dissatisfied. Registrars were significantly more satisfied than house surgeons. There were some relatively minor differences by region and specialty. There were no differences by gender, medical school, or whether partnered or nonpartnered. Hours of work, pay, holidays, rostering and other general working conditions were considered by most RMOs to be adequate to positive. The nature of the work was felt to be interesting, stimulating and providing an adequate level of responsibility. However, low morale seems endemic amongst RMOs in hospitals. There was a generally unfavourable view of hospital administration by all RMOs. Of those who claimed to be satisfied with their jobs, 28% stated that they would not re-enroll at medical school again if they had prior knowledge of their working conditions.
