During a hearing, called by their boss, Americans are careful, factual, cooperative. Most importantly they are discreet. Anger, impatience, any lack of self control is considered to be unprofessional.
The boss listens carefully to what each party to the conflict claims. In a formal hearing, within the legal system, parties providing testimony first swear that they will provide „the truth, the whole truth, nothing but the truth.“
The consequences for lying – perjury – are serious: a felony which can lead to a prison sentence for up to five years.
Perjury: the voluntary violation of an oath or vow either by swearing to what is untrue or by omission to do what has been promised under oath; false swearing.
American managers take very seriously their obligation, duty, responsibility to resolve conflicts within their organizations. Any attempt by a conflict party to manipulate that process is punished quickly and severely.
