The labor movement has proven to be the most effective tool to boost wages, promote workplace safety, and raise interracial solidarity between workers — so it is no surprise that business and conservative interests have spent decades trying to crush unions and prevent workers from forming them.

Over the course of his four years in office, President Donald Trump stepped up the assault, using the National Labor Relations Board (NLRB), the administrative body charged with enforcing national labor laws, to instead weaken unions and prevent nonunionized workers from organizing.

The attacks were largely successful, with union membership plunging to a record low of just 10 percent of workers in 2020.
