Since last year’s Labor Day, US unions have flexed their muscle in a way not seen in decades. They’ve scored some big victories amid some defeats. “It’s been a good year for unions,” said Art Wheaton, director of labor studies at Cornell University’s Industrial and Labor Relations school in Buffalo, New York. “You’ve seen a lot of successes and that will help going forward. I give them a B+. Not an A.” The Teamsters union used the threat of a record-setting strike by 340,000 members at UPS to achieve most of its bargaining goals, including significantly improved wages for the part-timers who make up most of the Teamster membership at the company. And a lower tier of wages for thousands of UPS workers hired since 2018 to let UPS move to six-day-a-week delivery was eliminated. Members voted overwhelmingly to approve the deal. Increasing number of strikes But while the Teamsters and longshore workers avoided a walkout, the US labor movement is engaging in an increasing in the number of major strikes. That’s far more than one significant strike a week, and it’s up 40% from the same period a year earlier. Meanwhile, other smaller strikes include one-day strikes at Starbucks locations that voted to unionize but haven’t yet reached an initial contract. When including those smaller strikes, there were 396 strikes over the course of the last 12 months, or more than one a day. Unions have also used short strikes, like the three-day action planned at Kaiser Permanente, to win many of their bargaining goals over the last year, from non-teaching school workers in Los Angeles to nurses in New York City. And unions that don’t get what they want from a first round of a strike can walk out again to increase the pressure on the company. Nearly 1,000 coal miners in Alabama returned to work at Warrior Met Coal in March after being on strike nearly two years, one of the longest US strikes in recent years. The United Mine Workers union never reached a deal on a new contract. Still, the unions have been helped by near-decades lows in unemployment and by a larger number of job openings than job seekers. That gives workers leverage to demand better pay, improved health care or simply a better work-life balance. Many of the health care workers unions say their main issue is lack of adequate staffing and the workers’ belief that they’re not able to provide the level of care they want without more help. Not just wages at issue The Biden administration and Congress stepped into a labor dispute late last year when freight railroad workers threatened to strike. Congress and Biden wanted to prevent damage to the US economy if the four major freight railroads shut down. But they took heat from the unions by voting to impose a contract that did not include sick days. More than 100,000 freight railroad workers received immediate 14% raises, back pay and raises totaling 24% over the five-year life of the contract. But most voted against the deals, complaining about quality of life issues, particularly the lack of sick days. Many saw the outcome as a defeat for the rail unions. But since that congressionally mandated contract took effect, the railroads reached separate agreements with the rail unions that gave most of those rail workers the sick days they sought. Some union members struggling Many unions’ members are struggling as they flex their muscle, most notably the roughly 160,000 actors who belong to SAG-AFTRA who have been on strike against major studios and streaming services since mid-July. Another 11,000 members of the Writers Guild have also been on strike against the same employers since early May. Observers see little end in sight for either of those strikes. While the unions halted production of shows and movies, the media and tech companies that would have paid for those productions are actually saving money from the lack of filming, which bolsters their recent cost-cutting efforts. The public has often sided with the union in these disputes. A Gallup poll released at the end of August showed Americans sympathize more with the television and film writers than with the production studios, with 72% supporting the writers and 67% supporting the actors. The public also sees unions having more power than in the past, and they approve of that, according to the poll. A record-high 61% believe unions help rather than hurt the US economy, topping the prior record set in a 1999 survey by six points. “Labor unions are enjoying a moment of high public approval and strong belief in the benefits they offer to workers, businesses and the economy,” said a Gallup statement. “Today’s striking workers may have a stronger hand in their negotiations than they would have had in the past given today’s elevated public support for unions.” That can raise the public relations risks for employers facing a strike. More major strikes loom A number of major labor disputes are still looming. Most notably, the United Auto Workers union is threatening a strike or strikes by as many as 145,000 members against one or more of the three major unionized US automakers — General Motors; Ford; and Stellantis, which makes vehicles under the Jeep, Ram, Dodge and Chrysler brands. The union which, according to the Gallup poll, has the support of 75% of Americans surveyed, laid out an ambitious set of goals at the bargaining table. Their demands include raises of 40% or more during the life of the contract, restoring the cost-of-living adjustments in pay to protect members from rising prices, and recapturing concessions made to the automakers earlier in the century when several automakers faced financial hurdles and as GM and Chrysler headed for bankruptcy and federal bailout. So far, the two sides don’t appear close to reaching deals with a strike deadline set for 11:59pm on September 14. Soon after that deadline, unions representing 85,000 health care workers, including nurses and other support staff, at Kaiser Permanente facilities in seven states nationwide are due to conclude their own strike authorization vote. A strike could start for those workers as soon as October 1.
