Timeline of strikes in 2023

A number of labour strikes, labour disputes, and other industrial actions have occurred in 2023. In the United States, the series of strikes has also been referred to as "hot labor summer,"  a play on Hot Girl Summer.

Background
A labor strike is a work stoppage, caused by the mass refusal of employees to work, usually in response to employee grievances, such as low pay or poor working conditions. Strikes can also take place to demonstrate solidarity with workers in other workplaces or to pressure governments to change policies.
