File a grievance in writing. Employees who belong to unions generally have specific grievance procedures they must follow. Non-union workers have other options, depending on the size and policies of their workplace. Report the problem to your immediate supervisor, unless he is the person doing the harassing. If a company has an internal grievance procedure or a human resources department, follow the procedures or contact HR. If there is no formal grievance procedure or HR department, go directly to the employer. You could also contact a legal services organization or a lawyer specializing in employment law.
