Trump just took an unprecedented assault on workers' rights.

Using “national security” as an excuse, and accusing federal worker unions of obstructing virtually everything, worker-hating Republican President Donald Trump ordered more than 30 federal agencies, most of them large, to trash their union contracts—now.
...“President Trump refuses to let union obstruction interfere with his efforts to protect Americans and our national interests,” OPM’s fact sheet blares, without evidence of unions obstructing any protections.

The two documents also provide a glimpse of Trump’s plans for private-sector workers, once he gets finished destroying federal workers and unions. In his first term, Trump White House aides, alumni of the far-right worker-hating Heritage Foundation, openly said “feds first, everyone else afterwards.”

“This executive order is the very definition of union-busting. It strips the fundamental right to unionize and collectively bargain from workers across the federal government at more than 30 agencies.”

This shouldn't surprise anyone paying attention. Trump has always been anti-union.
Trump has also gone after gutting the one place that Biden excelled at - the NLRB.

The Trump administration will choose a partner at the notorious anti-union law firm Morgan Lewis to be the next general counsel of the National Labor Relations Board, multiple sources tell the Prospect.

Crystal Carey is a former NLRB official from 2009 to 2018; she started as an intern with the Board and moved up to senior counsel, working on the Board and general counsel sides of the office. She became a partner last year at Morgan Lewis, which has been one of the most powerful management-side law firms in the country since the 1950s. Morgan Lewis attorneys have been involved in some of the most prominent labor battles in America since then, from the 1981 air traffic controllers strike to efforts by McDonald’s to resist the Fight for $15.

Let's compare that to the NLRB's record under BIden.
The NLRB has ordered corporations to reinstate more illegally fired workers in the first year of the Biden administration than it did during all four years of the Trump administration. The Biden administration updated Davis-Bacon standards to prevent federal construction contractors from paying below-market wages.
Biden's NLRB had made it easier for workers to organize as well.

On Aug. 24, the NLRB issued a final rule that will speed up union elections, screwing up Step 2 of employers’ union-busting playbook. The rule, effective Dec. 26, will eliminate common delay tactics that help employers: pointless waiting periods, the chance to request numerous extensions, and the opportunity to flood the process with irrelevant arguments.

According to the Economic Policy Institute, petitions for union elections grew by 53 percent between October 2021 and September 2022. Moreover, the rate at which workers win unions in NLRB elections climbed steadily during the first two years of the Biden administration, exceeding any level achieved under the previous administration.
In 2024, the Biden administration has picked up the pace.

In the month of April alone, it banned the noncompete clauses that can stop workers from taking another job in their same line of work if they quit, expanded eligibility for overtime pay to people making up to US$58,656 a year, up from its current cap of $35,568, and pushed pension funds to only invest in companies that adhere to high labor standards.

I recognize that not everyone considers this to be an important issue, but for me the status of labor unions is the weather-vane of the working class.
