Chipotle plans to hire 4,000 workers in one day on Sept. 9

The restaurant is calling the Sept. 9 event "National Career Day" and will open doors three hours early to take applicants.

The huge push is being seen by many as a sign the economy's improved and that there's increased competition among fast-food chains for workers. (Video via Chipotle)

Despite lower-wage industries seeing the biggest share of growth in the economic recovery, widespread strikes for higher wages have made it harder for the chains to hire.

A Chipotle executive told The Wall Street Journal, "The economy has been thawing, more restaurants are opening, and there are fewer job applicants than there were several years ago."

Chipotle didn't say anything about raising its wages, but in an earlier move to attract applicants, last month Chipotle started offering benefits, like tuition reimbursement, to some employees.

Chipotle currently has more than 60,000 employees. If it does hire 4,000 workers on Sept.9, it would increase its workforce by almost 7 percent. (Video via Chipotle)
