June 30, 2015: A look at CBSN's business headlines

Crunch time. Greece's bailout deal expires today and the country is running out of money. If Greeks vote "no" to an austerity plan this weekend, Greece could be forced to drop the euro as its currency.

OT. President Obama wrote an op-ed in the Huffington Post, calling for salaried workers who make less than $970 a week to be eligible for overtime. That's more than double the current level.

Financial boost. "99 percenters" are finally making more money. New data shows incomes rose 3.3 percent last year to more than $47,000. That's the biggest gain in 15 years.

Recall. Fiat Chrysler is recalling thousands of 2015 Jeep Grand Cherokees and Dodge Durangos because suspension components weren't treated for high temperatures. As a result, brakes could fail.

School meals. Starting this fall, American public schools will offer Chobani Greek yogurt as a meat substitute in school lunches.

Chew on this! And McDonald's, Burger King, KFC and Wendy's got some of the lowest customer satisfaction scores in years. Dunkin' Donuts is the only fast food chain to see improvement.
