The aim was to investigate (1) the prevalence of workplace bullying experienced by men and women in Swedish workplaces with a high level of stress dominated by one sex, (2) the prevalence of unjust treatment in these workplaces, (3) the relationship between workplace bullying and organizational climate, (4) the variability in bullying in these workplaces, and (5) the variability in organizational climate. These issues were examined using a self-assessment questionnaire in two types of workplace in Sweden: one male-dominated (juvenile detention care) and the other female-dominated (elderly care). About 20% of the participants experienced workplace bullying. There was a positive correlation between bullying and negative communication (strong effect size). There were no differences regarding the type of workplace. The internal consistency of the instrument was high, and we recommend its use in studies of workplace bullying
