Service Employees International Union and labor organizations representing firefighters and pipe trades workers have given a combined $1.1 million to the campaign to defeat Proposition 32, according to state records.
SEIU's California State Council of Service Employees Issues Committee gave $500,000. California Professional Firefighters Ballot Issues Committee donated $350,000 and California State Pipe Trades Council of the United Association contributed $250,000. The contributions were reported Thursday.
The Nov. 6 ballot measure would ban unions and corporations from using payroll-deducted funds for political purposes. It would also ban direct campaign contributions by either interest group. Both sides would be able to continue funding independent expenditure campaigns as they do now.
Defeating Prop. 32 is the top priority for labor unions, which rely heavily on payroll-deducted member dues to build their campaign war chests. Corporations use other means, such as contributions from executives and funds from their company treasuries to play in politics.
