It comes after one store was the scene of the mass shooting in El Paso, Texas Saturday and two employees were killed last week at a Mississippi store.
Thomas Marshall-- a worker at the e-commerce office in San Bruno-- organized the protest.
The walkout also had a moment of silence for the shooting victims.
ABC7 News reached out to Walmart for a response but we have not heard back. Walmart CEO Doug McMillon promised in a LinkedIn post yesterday to respond to the shootings in a "thoughtful and positive way."
