Labor giant Service Employees International Union spent $60 million on politics and lobbying as well as $19 million on the Fight for 15 movement in 2016, and now finds itself laying off headquarters staff.

The union's federal filing to the Department of Labor reveal that it experienced marginal growth in 2016, adding about 15,000 members from 2015. However, that increase did not correlate with financial growth as revenue fell by $17 million, fueling a $10 million budget deficit.

The union, which represents healthcare and public sector workers, spent $61.6 million on political activities and lobbying in 2016, roughly 20 percent of its $314.6 million budget, according to the filing.

However, those figures may underestimate its political spending. The union spent $19 million on activist groups and public relations consultants to assist with the Fight for 15 campaign, which has successfully pushed for dramatic minimum wage increases in New York, California, and Washington, D.C., according to an analysis from the Center for Union Facts.

The majority of that money went to worker organizing committees, local groups that organized and staged protests outside of fast food eateries such as McDonald's, which the SEIU has long targeted for unionization. Payments to those seven committees totaled $14 million and were classified as "support for organizing," rather than "political activities and lobbying."
