Not accepting their votes……

The California Legislature and the Brown administration apparently believe California’s farmworkers cannot be trusted to exercise their democratic rights. It’s the only plausible explanation for their efforts — via an administrative process and legislation — to invalidate the votes of 3,000 Fresno area workers who took part in a union election.

Workers at Gerawan Farming voted on a labor contract 10 months ago, but the Agricultural Labor Relations Board refuses to even count their votes. Instead, ALRB — created by a 1975 law signed by Gov. Jerry Brown — argues the election is invalid and is trying to force the workers to accept a controversial “no strike” contract.
