SAN FRANCISCO (KRON)—Dozens of activists are marching to the San Francisco headquarters of Twitter and Uber protesting for them to pay their fair share in the housing crisis and the homeless crisis in the Bay Area.

The march started around 4:30 p.m Wednesday. Protesters plan on delivering a 5 feet by 7 feet tax bill to both places.

Jobs With Justice San Francisco and other organizations are urging the community to pay their share through the Homeless and Housing Technology Tax. The organizations say the tax would raise $120 million each year to keep local businesses running and help people have the ability to afford to live in the Bay Area.
