A union represents an organized group of workers, whose purpose is to use their collective resources to manage and overcome job-associated challenges. Unions make decisions that better the conditions of their jobs, and serve as a liaison between workers and management. The reason for a letter to a group of union members might entail confirming a collective bargaining agreement, gaining support of a political cause, or another issue that affects union members.

Detail the Purpose of the Letter

Begin with the purpose of the letter. For example, describe to the union members the issue of concern. Include enough information so that people can identify with the cause or point that you are trying to make. Use urgent language if necessary, particularly when safety or a timeline is at stake. Detail how the situation could impact union members if is not addressed by them. Be as succinct as possible, so that anyone who reads the letter will understand the issue at hand.

Describe a Situation

Use a political angle that reflects what the union stands for. Describe how the union members contributed in the past to a political campaign. Use a slogan that union members understand. Include how the aims of the political issue relate to the current state of the union. Consider adding information about how the union can benefit currently from the political issue that is requesting support. Remind the union members about what the overall purpose of the campaign was about.

Refer to a Request

Consider opening the letter to a group of union members by referring to a request, such as obtaining a copy of an instrument like a collective-bargaining agreement. Describe precisely which document you wish to obtain and refer to the branch of the union and the parties in the agreement. Ensure that those reading the letter will understand why the request is being made and how it benefits the union members, if applicable.


When it comes to submitting a letter to union members, one size does not fit all. Each situation may differ from scenarios detailed in other letters. Make sure that your letter conforms to the standards, rights and procedures required in the union. Check with the union constitution or bylaws, if possible. Use sample letters from a website, such as Union Democracy, for a guide toward tailoring a letter for your purpose. Be sure that your letter can serve as a formal letter and be part of a paper trail to use in the future.
