San Francisco city union workers have taken over part of City Hall, as part of their two hour-long protest. Police arrested some people after they refused to leave.

They started marching from City Hall to Twitter's headquarters earlier Tuesday evening and then back to City Hall.

They have a list of demands and at the top is a higher minimum wage for companies that do business with the city.
