Not everyone on the BART board of directors is happy with the new behind-the-scenes labor deal announced this week.

The deal, which was worked out behind closed doors, gives BART’s 3,000 workers a 10.8 percent pay hike over four years. It also keeps the current benefits and bonuses earned during the 2013 strike fight in place.

By our calculation, the raises will cost about $8.8 million in the first year and grow to about $38 million per year by the end of the contract.

“It’s a bad deal,” said BART Director Zakhary Mallett, the board’s lone “no” vote on the last contract. “Extending a bad contract from 2013 for another four years is a bad thing to do.”

Mallett said BART operators and station agents already are among the nation’s highest paid, plus they will continue to receive benefits such as full family health care for $138 a month.

Then there are the $1,000 bonuses for every BART worker — from $347,819-a-year General Manager Grace Curnican to the $60,000- to $71,000-a-year train operators to the $48,000-a-year tool runner — if ridership exceeds expectations.

“It’s the equivalent of a 1½ percent raise in addition to the 10.8 percent,” Mallett said.

Fellow Contra Costa County BART Director Joel Keller also has questions — both about the total cost of the deal, which the board has yet to see, and the way it was reached.

The deal was cut during secret negotiations between BART management and union leaders a year before the current contract expires, and it was intended to eliminate public concerns over future work stoppages as the transit agency prepares to go to voters in San Francisco, Alameda and Contra Costa counties this fall with a $3.5 billion general obligation bond to fix the aging system. It would raise homeowners’ property taxes by $36 to $55 a year for 30 years, depending on location.

BART said details and cost estimates of the new contract would not be made public until after the unions had voted on it.

“At this point, I don’t know if it’s a good deal or a bad deal,” Keller said. “But the public deserves time to view it and scrub it before it’s voted on.”

State Sen. Steve Glazer, a vocal critic of BART’s last labor contract, called the proposed contract “a good first step,” but said it could be improved.

“For one, I don’t think that managers should get a ‘me-too’ clause,” Glazer said, referring to language common in public labor contracts that gives managers the same pay raises awarded to the workers on the other side of the bargaining table.

BART Director Gail Murray, however, said she was “very pleased” that a deal had been struck, largely because it would eliminate the “churning and disruption” that accompany labor negotiations and allow everyone to concentrate on improving the system.

How the new BART deal plays with the voters — most of whom do not ride BART — remains to be seen. But BART is betting big that the “no strike” implication is one voters most want to hear.

On the job: Former San Francisco Supervisor Ed Jew, who served nearly five years in federal prison for extortion and bribery after shaking down a local bubble tea outfit looking to expand in his district, is back working in Chinatown as a $17-an-hour cleanup ambassador.

“He probably averages less than $1,000 a month,” says Jew’s boss, George Chan, acting executive director of the Chinese Newcomers Services Center. The program targets new immigrants, and has a two-year, $150,000 grant from the mayor’s office to fight illegal dumping.

Jew has been working for the program on a contract basis for the past 1½ years, snapping photos of illegal dumping and calling in reports to San Francisco Public Works.

As an ambassador, Jew also meets with neighborhood merchants to hear their complaints and get out the word about stopping dumping, which these days includes dropping everything from stacks of cardboard to old televisions on Chinatown sidewalks.

“He’s doing a good job and is very active,” Chan said.

Golden: The giant gold “50” sculpture that was the backdrop for countless selfies at San Francisco’s Super Bowl City festivities in February has found a new home — the Active 20-30 Club of Santa Rosa, which also happens to be the 50th chapter of the Kiwanis-like charity group for young professionals.

The club bought the 12-foot-tall, plywood and gold laminate “50” for a bargain $300 from Building REsources, a nonprofit material recycling outfit in the Bayview.

The Super Bowl memento was trucked up to the Sonoma County Fairgrounds and reassembled inside the Grace Pavilion just in time for the club’s annual Battle of the Brews beerfest fundraiser last weekend.

“We just saw these big numbers and thought they would be cool to have at our event,” said event co-chair Brian Noble.

The “50” made for quite a show-stopping backdrop for the club’s Sacramento contingent, which posed in front of the flashy numbers wearing folk costumes right out of a Bavarian beer ad.
