A high-stakes union election is happening at a Mercedes-Benz plant near Tuscaloosa, Alabama, the only plant for the luxury automaker in North America. The fallout will be significant whether the workers at Mercedes-Benz vote to join the United Auto Workers union or not.

Consumers may be fed up with high prices at the store, but they’re still willing to splurge on travel. Disney’s parks and experiences revenue grew roughly 11% during the second quarter from the year prior. The company said that while attendance isn’t at the elevated levels seen following the end of Covid pandemic restrictions, it still rose at its US and Hong Kong Disneyland resorts. Other key players in the travel industry have reported a similar trend this earnings season. Americans, especially lower-income consumers, have pulled back spending at retailers as goods inflation outpaces wage growth.
