You are the HR Manager of a large organisation, and you have been asked to investigate why two of the large production teams have become dysfunctional. Various team members are complaining that the teams are taking on risks that not everyone agrees with, leading to a decline in commitment to team goals. The team leaders blame this decline to social loafing. During your sessions with team members, only one person mentioned that 'my teammate is good in product design discussions, but otherwise does little or no work'. Based on the scenario, which statement could represent a possible primary cause for the teams' dysfunctional behaviour? a. risk shift phenomenon and social loafing. b. role ambiguity/conflict. c. norm violation. d. risky shift phenomenon
