Answer:
4.Teach Fred about how decisions are made and communicated, as well as how conflict is handled.
Explanation:
Cultural differences are an important topic when it comes to adjusting to a new workplace. However, no matter how much the new employee knows about a specific culture, it is up to the manager or team leader to help him adjust.
The most effective way to help him is by teaching him <em>how decisions are made and conflict is handled</em>, in a straightforward manner. Since Fred is working in a team and not individually, it is essential for him to learn the basics of conflict management, as conflict handling varies immensely from country to country.
The same is applicable for decision making. He could not know the decision making practice in his new environment upfront. Some environments may encourage a more liberal way of making decisions, while some propose a strict protocol when it comes to making even the most trivial decisions.
Of course, checking him periodically and making sure he knows you're there for him are practices that can do only good. However, they are not critical for the issue.
