Do not keep your notes at your workplace. If you make a complaint to supervisors and administrators, do so in writing and keep a copy for yourself. Describe the problem and ways you've tried to resolve it. This creates a detailed written record of the incidents or conflicts which you've tried to settle informally. If internal channels exist, you may be able to resolve the problem informally through grievance procedures at your workplace.
Many employers have specific polices for handling discrimination problems.
Find out what they are. A personnel or affirmative action officer should have this information available to all employees. Involve your union If you are a union member, file a formal grievance through the union and try to get a shop steward or other union official to help you work through the grievance process. If you are a federal employee, follow federal guidelines on how to lodge a discrimination complaint. Remember, federal employees have a limited time frame in which to file a complaint.
