Public sector workers are apparently more financially secure, since they don't run the risk of being sacked overnight. However, some of these workers may be dissatisfied with the activities they do, but remain at work precisely because of this stability. This factor, among others, can lead to emotional problems and difficulty maintaining quality of life because of their work. This study aimed to assess quality of life (health-related) and personality (according to Trait Theory) among workers in the state of Mato Grosso do Sul. The instruments used were: The Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) to assess quality of life, and the Factor Battery of personality (BFP) to define personality traits. The results showed that women are more communicative and assertive; that older people tend to be calmer, more stable and have a better quality of life; that married people tend to be more relaxed and emotionally stable; and that people who sleep more have a better quality of life when it comes to social issues.
