Sam works for a large international manufacturing company. Managers at the company often assign team projects. Sam likes the group projects because he knows he will be team up with employees who will work hard on the projects, thus allowing him to dor a minimal amount of work. He will undoubtedly miss some of his group's meetings. What can managers at the company do to help groups deal with workers like Sam?

1. require group members to discipline other members when they "loaf"

2. help groups identify the potentially valuable contributions of each member

3. assign more members to groups so there are more people to pick up the slack

4. assign groups so that good workers are only grouped with good workers
