Thousands of workers around the U.S. are going on strike or threatening to do so heading into October, amid a recent surge of labor action activity in America and just one month before crucial midterm elections.

The Guardian reports that support for labor unions in the U.S. has grown over the past year, as a surge in organizing has resulted in workers winning union elections at major corporations including Starbucks, Amazon, Apple, Chipotle, Trader Joe’s, Google, REI and Verizon.

Union election petitions increased 58% in the first three quarters of fiscal year 2022, compared with 2021. Public support for labor unions is at its highest point since 1965, according to the most recent Gallup poll, with a 71% approval of labor unions in the U.S.

According to the labor action tracker at Cornell University, strikes in 2022 so far have significantly outpaced strike activity in 2021, with 180 strikes involving 78,000 workers in the first six months of 2022, compared with 102 strikes involving 26,500 workers in the first six months of 2021. The tracker recorded 41 strikes that started between 15 August and 15 September 2022, involving 35,250 workers.

Last October was also dubbed “Striketober” by the U.S. labor movement as a number of high-profile labor strikes and strike threats occurred throughout the month.
