Wendy’s has consistently revamped itself over the past few years through its menu – delicious burgers, fries and shakes –  but it hasn’t done much to update its staff.

To the dismay of all Wendy’s employees, the fast food chain announced that it plans to start re-interviewing its employees in an effort to only retain the best staff.

Wendy’s CEO Emil Brolick talked about the company’s top-to-bottom overhaul. The company has plans to build 20 and remodel 50 company-operated restaurants in the U.S. and Canada in 2012, reports QSRWEB.

“As part of our remodel effort –– which we call Image Activation – we are working to enhance the entire customer experience, including the restaurant design, inside environment, elevated food preparation standards and higher customer service standards,” said Brolick.

More than just a restaurant design, the Image Activation mission also includes a “people reboot” in which the company re-interviews entire staffs – initially at eight locations – keeping only the “5 star” employees. Wendy’s also is replacing underperforming general and district managers as needed. Since the implementation, the test stores’ service scores have increased dramatically, as have dine-in tickets.

Wendy’s also announced plans to expand its breakfast line in 2012, and revitalize its late-night operations.
