Oakland drivers who were led to believe that a strike Monday meant no parking enforcement on city streets got a rude awakening when a meter attendant decided to cross the picket line.

The worker, driving a city-issued car, was spotted ticketing cars in the vicinity of Broadway and 40th Street Monday morning. He refused to give his name to a reporter and said that he got paid well and didn’t support the strike.

Parking enforcement officers are among the 3,500 full and part-time city workers staging a one-day strike after their contracts expired Sunday. Police and firefighters are still on the job.

In alerting residents to the strike, city leaders had sent out notices stating that there would be “no parking enforcement.” However, the city can’t stop workers from crossing the picket line.

Sean Maher, a spokesman for Mayor Jean Quan, confirmed that one meter maid, whose shift ends at 3 p.m., had decided to work Monday. He did not respond to questions about whether the tickets would be forgiven.
