单选题 1 A growing number of companies are finding that small-group discussions allow them to develop healthier ways to think about work. People at all levels of the corporate structure are starting groups that meet weekly or monthly to talk over ways to make workplaces more ethical and just.
2 Several factors must be present for small-group discussions to be successful. First, it is important to put together the right group. Groups work best when they consist of people who have similar duties, responsibilities, and missions. This does not mean, however, that everyone in the group must think in lockstep.
3 All participants should agree on the group's purpose. Finding the right subject matter is essential. There are several ways to fuel the discussion: by using the company's mission statement, by finding readings on work and ethics by experts in the topic, or by analyzing specific workplace incidents that have affected the company or others like it.
4 Finally, the dynamics of the group should be balanced, and the discussion leader must not be allowed to overwhelm the conversation or the agenda. Groups work best when the same person is not always in charge. It is better to rotate the leadership for each meeting and let that leader choose the material for discussion.
