It certainly may be harassment but not all harassment is equal, or actionable. This means that your legal action will depend on the specific details of the comments being made. Comments about your clothing, appearance, body etc. being made by an employee of the opposite gender that make you uncomfortable are actionable and should be brought to HR’s attention. Similarly, crude or dirty jokes or emails or photographs being posted or passed around at work should also be brought to HR’s attention. It is very important that you review your company’s employee handbook to determine whom to bring this complaint to and the exact procedure for making the complaint. You should also be detailed and specific in your complaint to allow HR enough information to do its job. More importantly, let HR know about how you are being treated even if you don’t intend to sue or take any legal action.
