NEW YORK -- U.S. labor unions are once again flexing their muscles in the national spotlight.
The United Auto Workers' tentative agreements with Detroit's Big Three automakers could end the union's six-week strike. Gridlock persists in Hollywood between actors and major studios, while hospitality workers in Las Vegas, Detroit, Southern California and beyond are fighting for better pay and protections.
But despite historic walkouts and record contract deals seen this year, there's a lot stacked against labor organizers. Union membership rates in the U.S. have been falling for decades due to changes in the economy, employer opposition, growing political partisanship and legal challenges.
"Even though we're seeing stronger support for unions, [with] the highest popularity of union favorability in polls since at least the 1960s, translating the worker desire for representation into actual representation is really hard under our current system," Alexander Colvin, dean of Cornell University's School of Industrial and Labor Relations, told The Associated Press recently.
Still, some labor advocates see growing momentum. Here's where things stand.
Across the U.S., hundreds of thousands of workers have participated in strikes this year. Labor activism has surged in tandem with soaring costs of living and rising inequality, particularly the growing pay gap between employees and top executives. Those inequities only became more glaring during the covid-19 pandemic as U.S. corporations raked in record profits.
"It's kind of a perfect storm, [so] you see a lot of union movement these days," said Eunice Han, an assistant professor at the University of Utah specializing in labor economics.
The tightest U.S. labor market in decades is also giving workers leverage to challenge their employers.
The unemployment rate in the U.S. is close to 50-year lows and there are now about 1.5 open jobs for every unemployed person, according to recent government data.
Open jobs means American workers are quitting in higher numbers because they are confident of landing a better paying job. The unemployment rate of 3.8% further signals leverage for workers.
Success or partial victories in high-profile union fights can also inspire organizing across industries -- and bring lessons for future contract talks. A takeaway from the UAW's strike, for example, "is to act aggressively and creatively" while finding allies, said Cathy Creighton, director of Cornell University's Industrial and Labor Relations Buffalo Co-Lab and a former field attorney for the National Labor Relations Board.
UAW President Shawn Fain "didn't do things the same way that had been done in the past," Creighton added, noting the tactic of hitting General Motors, Ford and Stellantis at once through a buildup of targeted strikes, which were communicated to members on platforms like Facebook Live. Support from government officials, including President Joe Biden, also strengthened the campaign.
UNION RATES HAVE BEEN FALLING FOR DECADES. WHY?
While pickets lines seem to be everywhere this year, union membership rates have been declining for decades. Only 6% of U.S. private-sector workers belong to unions today, a sliver of the 35% that were union members in 1953.
Todd Vachon, an assistant professor in the Rutgers School of Management and Labor Relations, points to the post-World War II Taft-Hartley Act, which restricted the power of labor unions -- as well as factors like relocating manufacturing jobs overseas and an uptick in anti-union stances from both employers and lawmakers that grew in the '70s and '80s.
Vachon notes one pivotal moment in particular, when President Ronald Reagan fired all striking air traffic controllers in 1981.
"That sent a really clear signal to the business community that it's a-OK to be completely anti-union and to be so in a very belligerent way, because even the president of the United States is doing it," he said.
Separately, with the rise of the gig economy, some large companies have recategorized employees as "contractors," making it harder for them to unionize. And growth in industries that haven't had a strong history of union membership, such as technology, has also contributed to the decline in unionization.
Last year, the number of both public- and private-sector U.S. workers belonging to unions actually grew by 273,000, according to data from the Bureau of Labor Statistics. But the U.S. workforce grew at an even faster rate, meaning the percentage of those belonging to unions fell slightly.
WHAT LABOR LAWS AFFECT UNIONS TODAY?
The National Labor Relations Act of 1935 granted private-sector employees the right to unionize. A 1961 executive order from President John F. Kennedy allowed federal employees to organize. That came around the same era that states also began to pass labor laws for their own public workers.
Some states in the South and lower Midwest "will allow police and firefighters to collectively bargain, but not state employees. Or they'll let state employees bargain, but they can only bargain over wages," Vachon said. "That shows you how important the labor law is. It really sets the framework for which workers can either organize a union successfully or not."
A handful of states also have "right to work" laws which, in unionized workplaces, require unions to represent everyone regardless of whether individuals choose to pay dues or formally join. Such legislation has been criticized for undermining the financial resources and bargaining power of unions.
Attitudes toward unionization have become increasingly partisan, too, and also divided geographically. Politically "blue" states tend to have higher unionization rates than "red" states. Several states have also dialed back on union protections in recent years, Han said.
MORE CHALLENGES ORGANIZING TODAY
Unionization efforts have expanded but many are taking place where there is little history of organized labor, creating a higher bar for workers.
Colvin points to Starbucks workers who have seen union drives clipped in the last year. Starbucks has been accused of chilling organization by closing unionized stores and firing pro-union workers.
There are also limits for organizers under current labor law. That means that what worked in the auto workers' labor campaign, for example, may not be possible for other industries.
"We have a labor law that was designed in the era in the '30s and '40s, when auto plants of 10,000 workers [were organizing]," Colvin said. Starbucks is "split into these small coffee shops of 15 workers. ... They need to join together to have any kind of bargaining power against a big employer. But our labor law isn't structured to help them do that."
Service jobs can also be hard to organize due to part-time work and high turnover rates. The same can be said for Amazon warehouses, where there have been pushes for unions.
According to a Gallup poll, public approval of stronger unions now stands at 67%, down slightly from the 71% last year, but mirroring levels last seen in the 1960s. Creighton and others add that young people in particular are leading today's charge.
But the desire to organize can go only so far without policy change, experts say.
"We're absolutely at a turning point in people's consciousness," Vachon adds. "Whether that translates into actually a change of direction for union density, I think, is going to depend a lot on how that consciousness plays out in the political arena."
