A grievance letter is a formal document used to raise concerns, complaints, or issues regarding workplace policies, unfair treatment, discrimination, harassment, or any other matter affecting an employee’s rights or well-being. It serves as an official communication to the employer, HR department, or relevant authority, outlining the problem, providing details, and requesting appropriate resolution. A well-structured grievance letter should be clear, factual, and professional, specifying the nature of the complaint and any supporting evidence. This letter helps employees seek justice, promote fair treatment, and encourage a positive workplace environment by addressing conflicts and ensuring proper action is taken.
