Dave Dell Isola, the son and grandson of union members, grew up grateful for the family-sustaining wages and benefits that organized labor won for working people.

But he never fully grasped the might of solidarity until he and his wife, Barbara, and their two sons lost everything in an apartment fire. Dell Isola’s brothers and sisters in the United Steelworkers (USW) rushed to the couple’s side with financial assistance and other support to help them through the tragedy.

“They had me in tears,” recalled Dell Isola, now vice president of USW Local 12012, which represents hundreds of natural gas and propane industry workers in Massachusetts and New Hampshire.

The union bond is so powerful that corporate interests and their allies across the country desperately want to smash it.

Twenty-seven states already have falsely named right-to-work (RTW) laws on the books, and advocates of these union-busting measures now hope to enact them in New Hampshire and Montana.

In addition, corporations and their allies want to make another effort to ram the legislation through in Missouri, even though angry voters there rejected it by a landslide just a few years ago. And Republican lawmakers in Tennessee want to enshrine their anti-worker law in the state constitution, just to make it more difficult for wiser heads to repeal the legislation one day.

Working people only win fair wages, decent benefits and safe working conditions when they stand together. Solidarity also gives union members the grit to survive battles like the months-long lockout that Dell Isola and his co-workers at National Grid in Massachusetts endured during their successful fight for a fair contract.

Corporations want to rig the scales in their favor. They push RTW laws so they can divide workers—tear at the union bond—and exploit them more easily.

These laws allow workers to opt out of supporting unions while still reaping the benefits. Unions remain legally bound to represent workers regardless of whether they pay dues.

And just as corporations want, that erodes union activism and starves locals like Dell Isola’s of the resources they need to bargain with strength, enforce contracts, build solidarity and survive labor disputes.

When workers at Orchid Orthopedic Solutions tried to form a union, the company quickly brought in five full-time union-busters to torment them day and night.

The hired guns saturated the Bridgeport, Mich., plant with anti-union messages, publicly belittled organizers, harangued workers on the shop floor and asked them how they’d feed their families if the plant closed.

The months of endless bullying took their toll, as the company intended, and workers voted against forming the union just to bring the harassment to an end.

“Fear was their main tactic,” recalled Duane Forbes, one of the workers, noting the union-busters not only threatened the future of the plant but warned the company would eliminate his colleagues’ jobs and health care during a labor dispute. “Fear is the hardest thing to overcome.”

Legislation now before Congress would ensure that corporations never trample workers’ rights like this again.

The Protecting the Right to Organize (PRO) Act, introduced on Thursday, will free Americans to build better lives and curtail the scorched-earth campaigns that employers wage to keep unions out at any cost.

The PRO Act, backed by President Joe Biden and pro-worker majorities in the House and the Senate, will impose stiff financial penalties on companies that retaliate against organizers and require the National Labor Relations Board (NLRB) to fast-track legal proceedings for workers suspended or fired for union activism. It also empowers workers to file their own civil lawsuits against employers that violate their labor rights.

The legislation will bar employers from permanently replacing workers during labor disputes, eliminating a threat that companies like Orchid Orthopedic often use to thwart organizing campaigns.

And the PRO Act will empower the NLRB to force corporations into bargaining with workers if they interfere in union drives. That means an end to the mandatory town-hall meetings that employers regularly use to disparage organized labor and hector workers into voting against unions.

Orchid Orthopedic’s union-busters forced Forbes and his colleagues into hour-long browbeating sessions once or twice a week for months—and that was on top of the daily, one-on-one bullying the workers endured on the production floor.

Time and again over the past few years, as he fought to protect his co-workers at Bobcat’s North Dakota plant, William Wilkinson faced two obstacles.

One was the company. The other was a federal government that, instead of fulfilling its duty to safeguard workers, helped management exploit them.

Within hours of taking office on Jan. 20, however, President Joe Biden began to level the playing field and harness the strength of working people to tackle the huge challenges confronting the country.

Biden understands that only with a healthy, empowered workforce can America end the COVID-19 pandemic and rebuild the economy.

So in one of his first official acts, Biden fired Peter Robb, the union-busting corporate lawyer who wormed his way into the general counsel’s job at the National Labor Relations Board (NLRB) and then used his power to turn the agency against the people it was created to protect.

Robb, who directed agency field offices and set policy, thwarted organizing drives and advocated stripping workers of long-standing union protections. He determined employers had no obligation to bargain with unions seeking COVID-19 protections and even sided with employers who fired workers for voicing coronavirus safety concerns.

“Board charges used to scare the company. Now, they mean nothing,” said Wilkinson, president of United Steelworkers (USW) Local 560, who sensed Robb’s anti-worker animus rigging the scales in numerous cases that he filed on behalf of his members.

“No matter what, your case is dead before you get there,” Wilkinson said, recalling one dispute in which the NLRB refused to make Bobcat turn over financial data the union needed to assess a health insurance hike. “It’s Bizarro World. They have no interest in wrongdoing or whatever problem brought you there.”

Righting the NLRB will involve not only selecting a new, capable general counsel but, in a change from the former administration, installing board members committed to upholding labor law.

Biden’s housecleaning will ensure the agency returns to its mission of protecting labor rights, such as ensuring that the growing number of Americans who want to join unions—including employees of Amazon, Google and transportation services—can do so without harassment or retaliation.
