The 2022–2023 HarperCollins strike was a labor strike involving about 250 workers for HarperCollins, an American publishing company headquartered in the New York City borough of Manhattan. The workers, members of the United Auto Workers (UAW) Local 2110, went on strike on November 10, 2022, after failing to reach an agreement with the company regarding a new labor contract. The union members returned to work on February 21, 2023, after agreeing to a new contract that addressed many of the concerns they had initially had, including an increase in starting salaries and changes to some work regulations.
