Earlier this year, 55-year-old Glenn Johnson was making about $14,000 a year — or $7.93 an hour — at a Miami-area Burger King. He’d been in and out of the fast food industry for more than 30 years. Recently he watched as his employer reported a 37 percent increase in its quarterly profit, while continuing to resist a minimum wage increase that workers like Johnson have been fighting for.

Johnson described his daily routine as “pure hell.” It’s a nonstop effort to keep the store clean and the customers and his managers — most of whom are less than half his age — happy. “Sometimes, I get home and I’m so tired, I eat dinner, take a shower, lay down to watch TV, and I’m going to sleep,” he said. “Next morning comes. I’m tired, but I’m trying to make it.”
