At a time of staggering income inequality and stagnant wages, with unions facing an all-out assault from the Right, the teachers’ strikes have served as a rare bright spot for labor, proving that workers can still take on conservative politicians and their corporate backers. Now, with the Supreme Court’s Janus decision poised to bruise public-sector unions, Sanders is attempting to help revive the U.S. labor movement.

Over the spring, Sanders trekked across the country to stand with low-wage workers at corporations such as Disney and Amazon, spotlighting their efforts to win better treatment on the job. In May, he introduced the Workplace Democracy Act, a sweeping bill that would prevent employers from using certain anti-union tactics, make it easier for workers to unionize, and undo so-called right-to-work laws that drain unions of resources. The bill has secured support from almost a third of Senate Democrats, including prospective 2020 presidential contenders Elizabeth Warren, Kamala Harris and Cory Booker.

In a sprawling interview with In These Times, Sanders discusses how unions can respond to Janus, the fight to move the Democratic Party left, the recent victories of democratic socialist candidates and why he believes the 2018 midterms are the most important of his lifetime.

Why do you see labor issues as a critical rallying point in 2018?

In my view, there is really no way the middle class in this country is going to grow unless we build the trade union movement. Virtually all of the power rests with employers and large corporations. Workers without unions are finding it very difficult to get the kind of wages and benefits that they need.

The statistics are very clear that workers in union companies are earning better wages and have far better benefits than nonunion workers. And the working people in this country know it. In overwhelming numbers, workers want to join unions.

But it is increasingly difficult for them to do so. That is because of the power of employers to intimidate workers, to threaten to move their companies away, and to fire workers who are trying to organize. So it is very, very difficult now for workers to have a union. That has got to change.

You named your bill the Workplace Democracy Act. Why do you think it’s important for workers to be able to practice more democracy on the job?

It’s an issue that we don’t talk about as a nation very much. Millions and millions of people are waking up in the morning and saying, “Oh God, I have to go to work and I hate my job. I feel exploited. I feel powerless. I feel like a cog in a machine.” If we believe in democracy, it’s not just voting every four years, or every two years—it’s about empowering your whole life and having more say in what you do all day.

Workers who are in a union have the ability to have their voices heard and to express their discontent in terms of working conditions. So unions empower ordinary people to have a little bit more control over their lives.

Less than 11 percent of Americans currently belong to unions, and since taking office, the Trump administration has been waging an all-out assault on workers' rights. Yet in recent months, teachers have gone on strike across the country. Polling shows that younger people have a more favorable opinion of unions than older Americans. Are you optimistic about the future of the labor movement?

Yes, I am. With these teachers’ strikes—especially those taking place in so-called conservative states like West Virginia, Kentucky and Oklahoma—teachers have basically said, “Enough is enough.” We have to make sure that our kids get the educations that they need, that we attract good people into the teaching profession. Teachers almost spontaneously stood up and fought back and took on very right-wing legislatures. This was, I think, a very significant step forward.

The teachers may be the tip of the spear here, because you’ve got millions of people watching and saying, “Wait a minute, I work two or three jobs to make a living, 60 hours a week, and can’t afford to send my kids to college. Meanwhile, my employer is making 300 times what I make and he gets a huge tax break.”

I see an anger and a resentment among working families. They want an economy that rewards the work of ordinary people and doesn’t just allow the billionaires to get even richer. That’s what the teachers’ strikes are all about.

In terms of younger people, they’re looking at a nation where technology is exploding, where workers’ productivity has risen, and yet the average young person today has a lower standard of living than his or her parents. Younger people are saying, “What is going on? This is the wealthiest country in the history of the world—why am I still living at home? Why am I struggling to pay off my student debt 10 years after I graduated college? Why can’t I afford healthcare?” I think young people are smart enough to look around and say maybe we need unions to get the kinds of wages and benefits that working people are entitled to.
