Oct 2 (Reuters) - A tight U.S. labor market, the expiry of union contracts and high living costs have led to tough negotiations for pay hikes and benefits from workers and triggered strikes and protests across industries.

on Oct. 2.


The United Auto Workers (UAW) union has expanded its ongoing strike against the Detroit Three automakers - General Motors , Ford Motor and Chrysler parent Stellantis .

It has now expanded to 38 locations across 20 states.
