Right now, a lot of school districts across the country are making a pretty giant change to the way public education usually works. Facing teacher shortages and struggling to fill vacant spots, they are finding a new recruitment tool: the four-day school week.

Those districts are saying to teachers, "You can have three-day weekends all the time, and we won't cut your pay." As of this fall, around 900 school districts – that's about 7% of all districts in the U.S...

Union membership in the U.S. has been declining for decades. But, in 2022, support for unions among Americans was the highest it's been in decades. This dissonance is due, in part, to the difficulties of one important phase in the life cycle of a union: setting up a union in the first place. One place where that has been particularly clear is at the Volkswagen plant in Chattanooga, Tennessee...

When someone says "the economy is doing well"—what does that even mean? Like, for workers, for employers, for the country as a whole? According to what calculation? How do you put a number on it?

In 2017, The University of Minnesota asked comedian Maria Bamford to give their commencement speech. But the University may not have known what it was in for. In her speech, Bamford told the crowd of graduates how much the university offered to pay her (nothing), her counteroffer ($20,000), and the amount they settled on ($10,000), which (after taxes and fees, etc.) she gave away to students in the audience to pay down their student loans...

On today's show, we find out why. The answer includes a half a million vending machines, a 7.5 cent coin, and a company president who just wanted to get a couple of lawyers out of his office.

In 2007, Uruguay had a massive problem with no obvious fix. The economy of this country of 3.5 million people was growing, but there wasn't enough energy to power all that growth.

Ramón Méndez Galain was, at the time, a particle physicist, but he wanted to apply his scientific mind to this issue. He started researching different energy sources and eventually wrote up a plan for how Uruguay's power grid could transition to renewable energy...

When contract negotiations between Alaska Airlines and their flight attendants' union broke down in 1993, the union had a choice to make.

The union — The Association of Flight Attendants-CWA — knew that if they chose to strike, Alaska Airlines could use a plan. While Alaska Airlines technically couldn't fire someone on strike, they could permanently replace the striking flight attendants with new workers...
