It depends on how the person who is the target of the behaviour feels about it. If behaviour is unwelcome, then it is potentially harassment and should be stopped. Most people want to work in a friendly, relaxed environment, but friendly relationships have to be based on mutual respect and consideration. Workplace friendships, compliments and shared jokes are fine as long as everyone is free to choose if they want to be involved. Such behaviour only becomes harassment if it is unwelcome and causes a person offence or distress.
Harassment usually happens when people feel unable to object or do anything to stop the behaviour.
This may be because they feel powerless, because they are afraid they may be sacked or victimised if they do object, or because they are just too upset. Sexual harassment can be very damaging, both to the individual and to the University. Costs may include sick leave, the time taken to investigate complaints, the costs of recruiting and training replacement staff, preparation of legal cases and financial compensation to the complainant. Most people are reluctant to take any action when they have been sexually harassed because they fear the consequences of complaining. This is understandable, but experience has shown that harassing behaviour doesn t stop if you ignore it.
