The 2018 U.S. prison strike was a series of work stoppages and hunger strikes in prisons across the United States that began on August 21 and ended on September 9. The strike was conducted at least in part in response to the April 2018 prison riot at Lee Correctional Institution, which killed seven inmates and was the deadliest prison riot in the U.S. in the past 25 years. It was claimed that suspected strike participants and leaders were punished with solitary confinement, removing communication privileges, and prison transfers.
