Question: What is AFSCME Local 77, at the school where Eduardo Bonilla-Silver is a Sociology professor, an instance of?

full_context: Document 1: Civil rights movement: SNCC had undertaken an ambitious voter registration program in Selma, Alabama, in 1963, but by 1965 little headway had been made in the face of opposition from Selma's sheriff, Jim Clark. After local residents asked the SCLC for assistance, King came to Selma to lead several marches, at which he was arrested along with 250 other demonstrators. The marchers continued to meet violent resistance from police. Jimmie Lee Jackson, a resident of nearby Marion, was killed by police at a later march in February 17, 1965. Jackson's death prompted James Bevel, director of the Selma Movement, to initiate and organize a plan to march from Selma to Montgomery, the state capital.
Document 2: Dissolution of the Soviet Union: On March 4, 1989, the Memorial Society, committed to honoring the victims of Stalinism and cleansing society of Soviet practices, was founded in Kiev. A public rally was held the next day. On March 12, A pre-election meeting organized in Lviv by the Ukrainian Helsinki Union and the Marian Society Myloserdia (Compassion) was violently dispersed, and nearly 300 people were detained. On March 26, elections were held to the union Congress of People's Deputies; by-elections were held on April 9, May 14, and May 21. Among the 225 Ukrainian deputies, most were conservatives, though a handful of progressives made the cut.
Document 3: Affirmative action in the United States: Proponents of affirmative action argue that by nature the system is not only race based, but also class and gender based. To eliminate two of its key components would undermine the purpose of the entire system. The African American Policy Forum believes that the class based argument is based on the idea that non-poor minorities do not experience racial and gender based discrimination. The AAPF believes that "Race-conscious affirmative action remains necessary to address race-based obstacles that block the path to success of countless people of color of all classes". The groups goes on to say that affirmative action is responsible for creating the African American middle class, so it does not make sense to say that the system only benefits the middle and upper classes.
Document 4: Memphis sanitation strike: The Memphis sanitation strike began in February 1968 in Memphis, Tennessee. Following years of poor pay and dangerous working conditions, and provoked by the crushing to death of workers Echol Cole and Robert Walker in garbage compactors, over 700 of the 1300 black sanitation workers met on Sunday, February 11, and agreed to strike. They then did not turn out for work on the following day. They also sought to join the American Federation of State, County, and Municipal Employees (AFSCME) Local 1733. The sanitation strike was also the reason for Martin Luther King Jr.'s presence in Memphis, where he was assassinated.
Document 5: Black people: American University economist George Ayittey accused the Arab government of Sudan of practicing acts of racism against black citizens. According to Ayittey, "In Sudan... the Arabs monopolized power and excluded blacks – Arab apartheid." Many African commentators joined Ayittey in accusing Sudan of practising Arab apartheid.
Document 6: Near East: The basis of Simpson's unity is color and colonial subjection. His color chart recognizes a spectrum of black, brown and yellow, which at the time had been traditional since the late 19th century. Apart from these was "the great white race", which the moderate Simpson tones down to simply the white race. The great whites were appearing as late as the 1920s works of James Henry Breasted, which were taught as the gospel of ancient history throughout the entire first half of the 20th century. A red wavelength was mainly of interest in America. The eastern question was modified by Simpson to "The Problem of the Nearer East," which had nothing to do with the Ottomans but everything to do with British colonialism. Simpson wrote of the white man:
Document 7: Affirmative action in the United States: In 1976, a group of Italian American professors at City University of New York asked to be added as an affirmative action category for promotion and hiring. Italian Americans are usually considered white in the US and would not be covered under affirmative action policies, but the professors believed they were underrepresented. Libertarian economist Thomas Sowell wrote in his book, Affirmative Action Around the World: An Empirical Study, that affirmative action policies encourage non-preferred groups to designate themselves as members of preferred groups [i.e., primary beneficiaries of affirmative action] to take advantage of group preference policies.
Document 8: Multiracial Americans: The phenomenon known as "passing as white" is difficult to explain in other countries or to foreign students. Typical questions are: "Shouldn't Americans say that a person who is passing as white is white, or nearly all white, and has previously been passing as black?" or "To be consistent, shouldn't you say that someone who is one-eighth white is passing as black?" ... A person who is one-fourth or less American Indian or Korean or Filipino is not regarded as passing if he or she intermarries with and joins fully the life of the dominant community, so the minority ancestry need not be hidden. ... It is often suggested that the key reason for this is that the physical differences between these other groups and whites are less pronounced than the physical differences between African blacks and whites, and therefore are less threatening to whites. ... [W]hen ancestry in one of these racial minority groups does not exceed one-fourth, a person is not defined solely as a member of that group.
Document 9: Race (human categorization): In the United States, the practice of racial profiling has been ruled to be both unconstitutional and a violation of civil rights. There is active debate regarding the cause of a marked correlation between the recorded crimes, punishments meted out, and the country's populations. Many consider de facto racial profiling an example of institutional racism in law enforcement. The history of misuse of racial categories to impact adversely one or more groups and/or to offer protection and advantage to another has a clear impact on debate of the legitimate use of known phenotypical or genotypical characteristics tied to the presumed race of both victims and perpetrators by the government.
Document 10: Silent Vigil at Duke University: Immediately following the assassination of Martin Luther King, Jr., the Silent Vigil (also shortened to the Vigil) was a social protest at Duke University that not only demanded collective bargaining rights for AFSCME Local 77, the labor union for nonacademic employees, but also advocated against racial discrimination on campus and in the surrounding community of Durham, North Carolina. Occurring from April 4, 1968, to April 12, 1968, members of the University Christian Movement began planning a campus-wide vigil in memoriam of Dr. King. Another group of undergraduate students called for a protest march to address prevalent issues concerning the primarily African-American nonacademic employees at Duke in Local 77. Together, both student groups, along with the support of Local 77, most of the teaching faculty, and civilians not affiliated with the university, sparked a non-violent demonstration that involved over 2,000 participants, making it the largest in Duke's history.
Document 11: March on Washington Movement: The March on Washington Movement (MOWM), 1941 -- 1946, organized by activists A. Philip Randolph and Bayard Rustin as a tool to produce a mass march on Washington, D.C., was designed to pressure the U.S. government into desegregating the armed forces and providing fair working opportunities for African Americans. When President Roosevelt issued Executive Order 8802 in 1941, prohibiting discrimination in the defense industry under contract to federal agencies, Randolph and collaborators called off the march.
Document 12: Civil rights movement: The movement was characterized by major campaigns of civil resistance. Between 1955 and 1968, acts of nonviolent protest and civil disobedience produced crisis situations and productive dialogues between activists and government authorities. Federal, state, and local governments, businesses, and communities often had to respond immediately to these situations, which highlighted the inequities faced by African Americans. The lynching of Emmett Till and the visceral response to his mother's decision to have an open - casket funeral mobilized the African - American community nationwide. Forms of protest and / or civil disobedience included boycotts such as the successful Montgomery Bus Boycott (1955 -- 56) in Alabama; ``sit - ins ''such as the influential Greensboro sit - ins (1960) in North Carolina and successful Nashville sit - ins in Tennessee; marches, such as the Birmingham Children's Crusade and Selma to Montgomery marches (1965) in Alabama; and a wide range of other nonviolent activities.

Document 14: Assassination of Martin Luther King Jr.: President Lyndon B. Johnson was in the Oval Office that evening, planning a meeting in Hawaii with Vietnam War military commanders. After press secretary George Christian informed him at 8:20 p.m. of the assassination, he canceled the trip to focus on the nation. He assigned Attorney General Ramsey Clark to investigate the assassination in Memphis. He made a personal call to King's wife, Coretta Scott King, and declared April 7 a national day of mourning, on which the U.S. flag would be flown at half-staff.
Document 15: Race (human categorization): Eduardo Bonilla-Silva, Sociology professor at Duke University, remarks, "I contend that racism is, more than anything else, a matter of group power; it is about a dominant racial group (whites) striving to maintain its systemic advantages and minorities fighting to subvert the racial status quo."  The types of practices that take place under this new color-blind racism is subtle, institutionalized, and supposedly not racial. Color-blind racism thrives on the idea that race is no longer an issue in the United States. There are contradictions between the alleged color-blindness of most whites and the persistence of a color-coded system of inequality.
