Happy Labor Day! Whether a union represents you or not, your vote will help decide a November ballot measure that is keeping labor leaders up at night. Proposition 32, according to its advocates, “stops special interests from taking political deductions from employee paychecks to guarantee every dollar given for politics is strictly voluntary.” But critics say: “This measure says it prohibits unions from using payroll-deducted funds for political purposes. It says it also applies to corporations, so it sounds balanced. But 99 percent of California corporations don’t use payroll deductions for political giving; they would still be allowed to use their profits to influence elections.” Which argument influences you?
