Good samples of grievance letters are available at the websites Sample Letters 4 U and Letter of Grievance.

Letter of Grievance gives more in-depth examples of letters to be used in a professional capacity, with examples of how to address workplace policies and procedures respectfully while pointing out the employer's or employee's violations.
General grievance letters should include the author's full name and contact information, as well as the name and address of the company to which the letter is addressed. The correct person must be addressed in the letter; this is usually the manager. All facts must be addressed concisely and clearly, including the date and time of the incident, those responsible for the incident, and any witnesses. While addressing details, do not become emotional or irrational, and always conclude letters with words of gratitude for prior service.
Grievance letters aimed at places of employment must be well-informed and structured within the realms of employment law. Letters must be detailed and professional, and the author must be willing to back up his statements during court proceedings if the employer refuses to accept responsibility. Like general grievance letters, professional letters must be written without emotion and with a level head. Gratitude for employment and a statement indicating the wish for future fair treatment should wrap up the professional grievance letter.
