When your formal workplace complaint is about unfair labor practices, such as substandard working conditions, unfair pay, unequal treatment or your company's refusal to allow you to join a labor organization, submit a complaint to the National Labor Relations Board. Address the complaint to the regional director who handles complaints in your state. Use supportive details and specific examples to back your claim. The regional director will decide if your complaint requires further investigation and notify you of the results. Visit for more information on how to submit a formal complaint.
