Unions can be a powerful aid to workers because collective bargaining keeps wages high and benefits stable. In return for offering the high pay and benefits, unions promise strict performance standards and adherence to workplace rules. If an employee does not deliver, he will have a hearing with the union and usually he will receive a warning. If the violation is repeated, the employee will have another hearing, and will usually be fired. At that point, he may choose to appeal the decision.

Type your address. Skip a line. Type the date. Skip another line. Type the name of your union representative, your company name, and the company address on separate lines.

Create the salutation by typing "Dear Mr./Ms. (Last name)" followed by a colon.

Begin the letter by explaining that you are appealing the union decision. Give your name and your union ID number, if applicable, and explain the violation that occurred.

Detail the reasons why you should not be fired or the reasons why you should not receive a reprimand. Explain the union rule and why your circumstances were different. For example, if you were reprimanded for improperly scanning labels on packages and your scanner was not working correctly, explain that in detail and attach any evidence that would support your claims, such as an affidavit from your supervisor that you changed scanners because of the problem.

Close the letter by thanking your representative for their time. Provide your phone number and any other contact information the representative may need.

Type "Sincerely," and skip three line spaces. Type your full name. Print the letter and sign your name above the typed name.

Give the letter to your union representative directly, along with any appeal forms or supporting documentation.
