Union Bug Printing: What It Is & When You Need It
A union bug is more than a small mark on a printed piece: for campaigns, labor organizations, and other groups, it can document that the work was produced in a union shop. Learn what the label means, who may request it, and how to plan a union-printed order.
What Is a Union Bug?
A union bug is a small logo, emblem, or imprint that identifies the labor union or union-affiliated program connected to a printed piece. It signals that the work was produced under the shop's union arrangement and is commonly placed in a bottom corner or another standard location. The mark is part of the production specifications, not artwork a customer has to recreate. At Cornerstone, union bug placement is handled during production and the appropriate mark is included in the final design before press.
Who Requires Union-Printed Materials?
Union printing is often requested by political campaigns, labor organizations, municipalities, nonprofits, and civic groups. A labor endorsement, party rule, collective bargaining or procurement requirement, or an organization's own policy may call for a union-printed piece. These requirements vary by organization and project; the union bug is not a blanket legal requirement for every campaign or mailing. If a specific label, location, or wording is required, provide that instruction when requesting a quote so it can be confirmed before production.

Frequently Asked Questions
What is a union bug?
A union bug is a small printed mark or emblem identifying the union-affiliated shop or labor program responsible for producing a piece. It is usually placed in a bottom corner or another unobtrusive location. The exact label and placement can vary, so a printer should confirm the appropriate mark for the job.
Why do political campaigns require union-printed materials?
Some campaigns are asked to use union printing by a labor organization, party, endorsement, contract, or internal campaign policy. The union bug provides a visible record that the material was produced in a union shop and can be important when demonstrating labor support. It is not a universal legal requirement for every political campaign, so confirm the specification with the organization making the request.
Which Cornerstone products are available union-printed?
Cornerstone offers union palm cards, union envelopes, union postcards, and union letters through its shop. Brochures, letterhead, and other campaign or organizational materials can also be discussed as part of a union-printing quote. The best product depends on whether you are canvassing, mailing, or preparing formal correspondence.
Does union printing cost more?
There is no single union-printing price or automatic surcharge. The total depends on the product, finished size, stock, coating, quantity, artwork, and whether mailing is included. Request a quote with your specifications so the production requirements and any union-label needs can be confirmed together.
