An argument broke out between a manager and one of his employees; HR was asked to investigate. After interviewing both the employee and the manager, the HR director overheard the employee saying, "I wish this were the olden days. I'd take this argument out in the street and solve it without anyone's help." Because Clearwater Electronics has a zero-tolerance policy for workplace violence, with prominent signage in a number of visible locations in the plant, the employee was immediately terminated. Why did this incident of workplace violence occur?
