Sexual harassment refers to unwanted sexual advances or sexually-oriented remarks or behaviour that are unwelcome by another person. Flirting and joking are fine if they are consensual and wanted. But sexual harassment poisons the environment. Harassment is ultimately about inequalities of power. The same action done by a woman might not bother a man because, in general, our society has not given women power over men. Men can join women in opposing sexual harassment by supporting efforts in our workplaces and schools to create a healthy and productive environment.
