The present study examined how the relationship between nurses' perception of their environment and their work values could explain their job performance and whether they intended to quit their jobs. A survey (N=346) and a focus group (N=6) were used to collect data. The results revealed that nurses' job performance was maintained in an environment where they received few professional incentives due to their professionalism. In contrast, negative environmental characteristics directly impacted on nurses' intention to quit their jobs. The present study provides new insights into nurses' work behaviour.
