"The union reports, filed with the Department of Labor, list compensation for all union employees and officers. Salaries make up the biggest portion, but other benefits can include tens of thousands of dollars for meal allowances, mileage allowances and entertainment. Health care and pension contributions are not specifically addressed.
The reports show that assets of the various labor unions run into the hundreds of millions of dollars, and payrolls rival midsize companies. Among the Top 10 unions, dozens of top officials have salary-and-benefit packages that rank them among the top percentage of income-earners in the country."
