The three biggest franchise brands in the world are all embroiled in disputes with their U.S. franchisees.

This week’s episode of the Restaurant Business podcast “A Deeper Dive” features John Gordon, a restaurant consultant out of San Diego, who talks about these disputes and why they’re happening.

The three brands are McDonald’s, Subway and 7-Eleven. At McDonald’s, franchisees have been pushing back against a $70 million technology fee and could take legal action to stop it.
