Whether under the U.S. LMRDA (Labor Management Reporting and Disclosure Act) or similar public sector laws, unions generally are required to file various information reports with a government agency and to make the information available to their members.  For private sector employees, these Labor Management or “LM” reports are public information, available to you from the local office of the federal Department of Labor, or by ordering from that agency’s website (www.dol.gov).  They are worth tracking down if you wish to obtain detailed information as to a union’s financial status, such as assets and liabilities, salaries and expenses of union officers and staff, and any loans the union may have granted to members or businesses.
