Hundreds of dissatisfied Bay Area workers, struggling to pay a skyrocketing cost of living and upset by campaign promises made by President-elect Donald Trump, took to the streets Tuesday to demand higher pay and improved workers’ rights during a nationwide day of protest.

Protesters including fast-food workers, airport employees, child care workers and Uber and Lyft drivers shut down an intersection in East Oakland in the morning. Another group marched peacefully at San Francisco International Airport in the afternoon.

The demonstrators joined thousands of workers marching in cities across the U.S., including Chicago, Detroit, New York and Los Angeles, as part of “Fight for $15,” a 4-year-old movement campaigning for a national $15 minimum wage and union rights. In California, a law passed this year will raise the minimum wage to $15 by 2022, but organizers say many of their workers still cannot afford to live in the Bay Area.

“Our fight is more for the idea that if you’re working full time, you should be able to live in the area that you work,” said Steve Boardman, spokesman for the SEIU United Service Workers West, a union that represents airport workers including baggage handlers, security and wheelchair attendants.

In Oakland, more than 100 protesters blocked the intersection of 98th Avenue and International Boulevard for more than an hour early Tuesday. Police arrested 27 protesters, cited them for obstructing a street, and released them later in the morning, Oakland police Officer Marco Marquez said.

At SFO, nearly 1,000 workers demonstrated outside the international departures terminal, carrying signs with messages such as “No to the border wall,” “Homes for all” and “Uber & Lyft you can deactivate my account but not me.” There were no arrests, according to the San Francisco Police Department. Airport spokesman Doug Yakel called the protests “very peaceful” and said they did not disrupt airport operations.

Tuesday’s demonstrations marked the first time Uber and Lyft drivers — who can’t unionize and don’t have to be paid minimum wage because they are independent contractors, not employees — joined the Fight for $15 movement.

“Drivers are working a lot more and they’re making a lot less,” said Edward Escobar of San Leandro, an Uber and Lyft driver and an activist for independent contractor rights.

Eduardo Dos Santos, a 54-year-old San Bruno resident, was one of a few dozen Uber and Lyft drivers who gathered before the airport protest to voice their grievances with the ride-hailing companies. Dos Santos is struggling to make ends meet on his driver’s wages, he said, and doesn’t have the money to pay next month’s $1,300 rent.

“Now I’m thinking of applying for unemployment, because it doesn’t make sense to (drive),” he said. “I’m not going anywhere. I’m just going deeper into the hole.”

Kevin Prasad, who works as a security officer at SFO, joined Tuesday’s protest because he says the wages he and his coworkers earn aren’t enough to live on in the Bay Area, which has become one of the nation’s most expensive regions. An Army veteran who served in Kuwait, Prasad recently had to suspend his aviation operations studies at San Jose State University because he can’t afford classes.

“I barely make it,” said Prasad, who earns $15 an hour and lives in San Francisco. “I’d like to further advance myself, but I can’t do that if all my money is going toward rent, food, transportation.”

Prasad’s feelings were echoed in cities across the nation Tuesday.

In Chicago, hundreds of protesters at O’Hare International Airport were outside terminals chanting, “What do we want? $15! When do we want it? Now!” Protesters briefly shut down a downtown St. Louis McDonald’s restaurant, blocking the drive-thru for about 30 minutes. In Massachusetts, a state senator was among nearly three dozen people arrested after they sat down on a Cambridge street during a demonstration.

About 25 of the 350 protesters in New York City were arrested. One protester, Flavia Cabral, 55, struggles to make ends meet with two part-time jobs.

“All these people don’t have savings because we’re working check to check,” Cabral said. “We have to decide what we are going to get: We’re going to pay rent or we’re going to put food on the table or we’re going to send (our children) to school.”
