Sit-in

A sit-in or sit-down is a form of direct action that involves one or more people occupying an area for a protest, often to promote political, social, or economic change.

The Fellowship of Reconciliation (FOR) and the Congress of Racial Equality (CORE) conducted sit-ins as early as the 1940s. Ernest Calloway refers to Bernice Fisher as "Godmother of the restaurant 'sit-in' technique." In August 1939, African-American attorney Samuel Wilbert Tucker organized a sit-in at the then-segregated Alexandria, Virginia, library.Congress of Industrial Organizations (CIO) labor delegates had a brief, spontaneous lunch counter sit-in during their 1947 Columbus, Ohio, convention.

In one of the earliest use of sit-ins against racism, followers of Father Divine and the International Peace Mission Movement joined with the Cafeteria Workers Union, Local 302, in September 1939 to protest racially unfair hiring practices at New York's Shack Sandwich Shops, Inc. According to the New York Times for September 23, 1939, on Thursday between 75 and 100 followers showed up at the restaurant at Forty-first Street and Lexington Avenue, where most of the strike activity has been concentrated, and groups went into the place, purchased five-cent cups of coffee, and conducted what might be described as a kind of customers' nickel sit down strike. Other patrons were unable to find seats."

In May 1942, James Farmer, Jr., an organizer for the Fellowship of Reconciliation, led a group of 27 people to protest the racially discriminatory no-service policy of the Jack Spratt Diner on 47th Street in Chicago. Each seating area in the diner was taken by groups that included at least one black person. The peaceful patrons, several from the campus of the nearby University of Chicago, then tried to order; all were refused. The police were called, but when they arrived they told the management that no laws were being broken, so no arrests were made. The diner closed for the night but thereafter, according to periodic checks made by CORE activists, it no longer enforced its discriminatory policy.
