From strikes to new union contracts, Labor Day's organizing roots are especially strong this year

Labor Day is right around the corner, along with the big sales and barbecues that come with it. But the activist roots of the holiday are especially visible this year as unions challenge how workers are treated — from Hollywood to the auto production lines of Detroit.

The early-September tribute to workers has been an official holiday for almost 130 years — but an emboldened labor movement has created an environment closer to the era from which Labor Day was born. Like the late 1800s, workers are facing rapid economic transformation — and a growing gap in pay between themselves and new billionaire leaders of industry, mirroring the stark inequalities seen more than a century ago.

“There’s a lot of historical rhyming between the period of the origins of Labor Day and today,” Todd Vachon, an assistant professor in the Rutgers School of Management and Labor Relations, told The Associated Press. “Then, they had the Carnegies and the Rockefellers. Today, we have the Musks and the Bezoses. … It’s a similar period of transition and change and also of resistance — of working people wanting to have some kind of dignity.”
