An employer has no business with a man's personality. Employment is a specific contract calling for a specific performance... Any attempt to go beyond that is usurpation. It is immoral as well as an illegal intrusion of privacy. It is abuse of power. An employee owes no "loyalty," he owes no "love" and no "attitudes" - he owes performance and nothing else. .... The task is not to change personality, but to enable a person to achieve and to perform.
