Why Joe Biden is wooing unions

In his plan for rebuilding infrastructure and addressing climate change, Joe Biden mentions unions 32 times, repeatedly calling for jobs that pay well and also offer the chance to join a union.

That partly reflects Biden’s drift to the left, as he tries to build a bridge to liberal Democrats who back Senators Bernie Sanders and Elizabeth Warren. But Biden’s pitch for unions could work with moderate voters too, since unions have gotten more popular as they’ve become less common.

Union membership has been falling steadily since the 1970s, with just 10.3% of workers belonging to unions today. That’s down from a peak of around 32% in the early 1950s. About one-third of government workers belong to a union, but in the private sector barely 6% do. Unions have declined as manufacturing jobs have gone overseas, employers have found ways to avoid costly union contracts and some workers with the choice have rejected unions.

Some economists think the decline of unions is one of the reasons household income has stagnated, while income inequality has dramatically worsened. That may explain why unions have been gaining popularity after a long slide. Approval of unions fell from 75% in the 1950s to a low of 48% in 2009, according to Gallup surveys. That was around the time many Americans felt greedy, corrupt labor unions contributed to the bankruptcies of General Motors and Chrysler. But union approval rebounded to 64% in 2019, even as union membership shrank during the last decade.

The United Auto Workers union is accusing General Motors of violating a national contract by using temporary workers instead of employing full-timers who were laid off from its factories. The union filed a federal lawsuit in Cleveland alleging that GM has temporary workers at its pickup truck plant in Fort Wayne, Ind. The lawsuit says GM has about 1,000 workers on layoff from several factories who should be working at the plant. (AP Photo/Tony Dejak, File)

As a longstanding Washington Democrat, Biden might seem like a natural ally of labor unions. But unions grew disillusioned with Democrats during the Obama administration, when Biden was vice president. Obama generally supported a free-trade agenda that labor unions felt weakened their job security. He also gave tepid support to legislation that could have expanded union membership. And the Affordable Care Act, passed in Obama’s second year in office, included a provision to tax generous health coverage plans like those many unions have negotiated. Congress repealed that unpopular tax last year, when Trump was president.

Trump won the union vote

Donald Trump’s protectionist trade agenda in 2016 helped him with union members, including some who supported Bernie Sanders in the Democratic primary elections. Hillary Clinton won 55% of the union vote in 2016, with Trump getting 38%. But Clinton’s pull was down from 2012, when Obama got 65% of the union vote and Mitt Romney got just 30%. Those additional union votes for Trump were probably enough to put him over the top in Pennsylvania, Michigan and Wisconsin, securing the electoral college win in 2016.
