Fast food workers and union organizers rallied outside a downtown Denver McDonald's on Thursday, calling for the restaurant giant to raise wages for all its employees.

The food chain announced Wednesday that it would raise wages for workers by roughly one dollar an hour nationwide. But the pay raise does not apply to workers who are employed by individually-owned franchise restaurants, where the vast majority of McDonald's workers are employed. That's about 750,000 employees at 12,500 McDonald’s in the U.S., operated by about 3,100 franchisees, the New York Times reported. Franchise owners set their own pay and benefits.

Andrew Olson is employed at a corporate-owned Aurora McDonald's where workers will see a pay bump. But he feels that all employees should see raises regardless of the restaurant they work for.

“It's not fair for, you know, only a slight amount of us who got lucky enough on the random occasion while looking for a job to be working at a corporate McDonald’s,” he said.
