I would agree with with you Jay..!
But this needs lot of guts..coz..firstly, Monica is a women, the issue happend is not for Monica and the employee sued was not in the organisation currently and may be some of the people of Organisation might not want to involve in such kind of issues.
Monica if you would really like to teach a lesson to him, better find a good job when ur service is damn required for ur company, take all your prospectus from Organisations, after notice period is issued and on the last day of your working, insult him badly for the mistake done by him infront of all the staff of his employees with whom he have to work from next day on wards.
However, ensure that you do not fall in risk in teaching lesson to him. I really appreciate you for such revolution.
