What is a "general strike," and is it time to have one?

A couple of days ago Teen Vogue published an article about 'resistance, rebellion, and revolution' (see Cory's post about it). Today, Teen Vogue has another excellent article along the same lines. It's written by Kim Kelly and is called General Strikes, Explained. With the Trump Shutdown threatening to disrupt functioning society, it's a good time to read this.
A general strike is a labor action in which a significant amount of workers from a number of different industries who comprise a majority of the total labor force within a particular city, region, or country come together to take collective action. Organized strikes are generally called by labor union leadership, but they impact more than just those in the union. For example, imagine the scenario if thousands in your town or city — no matter what their job was or whether or not they were in a union — got together and decided to go on strike to protest police brutality, as happened in Oakland, California, in 2011, after Iraq veteran Scott Olsen was critically wounded by local police when they stormed the Occupy Oakland encampment. The community declared a daylong general strike that ultimately saw thousands of people shut down the Port of Oakland (which was more of a symbolic protest, but still it got the job done).
