The Improving CTU Act of 2026 requires labor unions to include audit results in their financial reports submitted to the federal government. Specifically, the bill amends federal labor law to mandate that unions disclose any audit findings related to their finances or financial transactions that the union has access to. The legislation also requires unions to make these financial reports more accessible to their members by publishing the information on their website or, if they lack a website, by providing copies to members upon request. The bill applies to all financial reports submitted six months after it becomes law. This legislation aims to increase financial transparency within labor organizations and give union members better access to information about how their unions manage money.
