Some examples of psychological harassment include:

• Making rude, insulting or offensive remarks.
• Making gestures meant to scare a person; getting back at someone.
• Discrediting the person: spreading rumors, making fun of him, humiliating
  him, calling into question his beliefs or his private life, shouting abuse
  at him or sexually harassing him.
• Belittling the person: forcing him to do tasks that are belittling or below
  his skills.
• Preventing the person from expressing himself: yelling at him, threatening him,
  constantly interrupting him, not letting him speak to others.
• Isolating the person: no longer talking to him at all, pretending he does not
  exist, distancing him from others.
• Making fun of a person’s beliefs, tastes and political choices.
