Germans will avoid an open hearing at almost all costs. The airing of grievances ﹣ argument vs. counter-argument in front of the next level of management﹣only increases tension, making resolution more difficult. Instead, the conflict resolver interviews each party separately and on a one-on-one basis.
Americans expect a fair hearing. The process of justice begins when the conflict parties, in the presence of each other, make their case before the judge. In the American culture self-defense is only possible when one knows what the other side is accusing them of. A hearing almost always takes place.
