Does my boss need to be harassing me specifically for it to count?

Harassment need not committed by an employee’s supervisor or a member of management to be illegal. In addition to actions and conduct by management, a co-worker or non-employee (such as a contractor, vendor or guest) could potentially create a hostile work environment for an employee. A person making a claim of hostile work environment harassment need only be affected by the harassing conduct, not necessarily the employee to whom the conduct is directed.
