Examples of union violence since 1925 include:
2012 - Union workers protesting right-to-work legislation in Lansing, Michigan destroyed a tent run by Americans for Prosperity. People were inside the tent but managed to escape before the collapse. Additionally, hot dog stand operator Clinton Tarver, a popular vendor around the Capital area who was hired to provide catering for AFP, lost his equipment, condiments, coolers, and food in the collapse. According to Tarver (an African American), union workers, who had incorrectly assumed he was supporting AFP, called Tarver an "Uncle Tom nigger". A union worker also punched conservative comedian and Fox News contributor Stephen Crowder, resulting in a chipped tooth and a minor cut on the forehead. Another worker threatened to kill Crowder with a gun.
2011 - It was reported on September 9, 2011 that members of the International Longshore and Warehouse Union (ILWU) frightened security guards, dumped grain, and vandalized property belonging to EGT, LLC, over a labor dispute. No one was hurt, and no one had been arrested at the time the incident was reported. District Judge Ronald Leighton later issued a preliminary injunction against the ILWU citing their reported behavior.
1997 - On August 7, 1997, teamsters Orestes Espinosa, Angel Mielgo, Werner Haechler, Benigno Rojas, and Adrian Paez beat, kicked, and stabbed a UPS worker (Rod Carter) who refused to strike, after Carter received a threatening phone call from the home of Anthony Cannestro, Sr., president of Teamsters Local 769.
1996 - On 19 August 1996, Australian unionists physically broke into the Australian Parliament & fought Australian Federal Police during the 1996 Parliament House Riot.
1993 - Eddie York was murdered for crossing a United Mine Workers (UMW) picket line at a coal mine in Logan County, West Virginia, on July 22, 1993. Like the 1990 NY Daily News strike, criminal charges under the Hobbs Act were declined, with the FBI and Justice Department citing the Enmons case.
1990 - on the first day of The New York Daily News strike, delivery trucks were attacked with stones and sticks, and in some cases burned, with the drivers beaten. Strikers then started threatening newsstands with arson, or stole all copies of the Daily News and burned them in front of the newsstands. James Hoge, publisher of the Daily News, alleged that there had been some 700 serious acts of violence. The New York Police Department claimed knowledge of 229 incidents of violence. Criminal charges under the Hobbs Act were declined, however, citing the aforementioned Enmons case.
1986/1987 - three union workers set fire to the Hotel Dupont Plaza in San Juan, Puerto Rico, while other union members staged a fight as a distraction. The union, said to be affiliated with the Teamsters, was having a labor dispute with management over pay and health care. Ninety-seven people were killed, none of whom were union members. Most bodies were burned beyond recognition.
1986 - During protests by the International Brotherhood of Electrical Workers Local 1547 against a non-unionized workforce getting a contract, picketers threatened and assaulted workers, spat at them, sabotaged equipment, and shot guns near workers. In 1999, the Alaska Supreme Court ruled that the union had engaged in "ongoing acts of intimidation, violence, destruction of property", awarding the plaintiff $212,500 in punitive damages.
