The study is based on the questionnaire related to work teams (n=595) in public and private sector organisations in Finland. The data consists of total networks of teams (n=98) (communication, advice, and emotional support) as well as performance measures of the team as evaluated by the managers of the organisations. Team research has paid scant attention to the relational structure of teams. Moreover, the organizational context in which teams operate has been overshadowed by the analysis of mental states of team members. Consequently, the first aim of the study is to elaborate whether the performance is related to network structure of the teams. The second aim of the study is to examine whether organizational context shapes the social structure of the teams.
