Step-by-step explanation:
The conflict management strategy that Will employs, which involves playing down the differences while emphasizing the common interests of the parties involved, is known as smoothing. This technique aims to alleviate the tension in a conflict situation by focusing on areas of agreement and trying to find a pleasant middle ground without necessarily resolving the deeper issues. Such an approach is distinguished from compromise, problem solving, or avoidance in that it seeks to calm the situation and maintain harmonious relationships rather than pursuing an immediate permanent solution or competition.
