This monograph studies the need and possibility of preserving the individual's right to personality in the event of moral damage in the workplace. It demonstrates important and necessary aspects to inform the possible scope of the damage. It addresses the right to personality from the perspective of the dignity of the human person, violated by the practice of harassment, and the difficulty of proving its occurrence when seeking judicial protection. It points to relevant doctrinal concepts, inherent to social and human aspects, to raise awareness among individuals who seek their dignity in a healthy working environment. It reflects on the consequences of moral damage at work, which are not always externalised, but which affect the subjective rights of human beings. Some means of proof admitted in labour proceedings are presented, as well as the conditions under which they can be used in court so that conduct can be effectively studied, denounced, curbed and punished.
