Teamwork. Teamwork was measured by three-item summated scale. A sample item is "My work group cooperates with other work groups to achieve business objectives" and "My work group looks for ways to change processes to improve
productivity." These items are measuring the belief that an employee is part of an effective and collaborative team. The higher the score in the measure, the more positive respondent felt about being part of a collaborative team. Cronbach's alpha for this measure was .74.
