Yolanda Quesada was fired when a background check revealed she shoplifted in 1972.
"I'm very good at what I do for Wells Fargo," Quesada says.
Quesada says she was a good employee, and has the pins, certificates and photos to prove it, but, her supervisor walked her out the door last week after more than five years of service at Wells Fargo.
"I think there's more important things in life than something I did 40 years ago," Quesada says.
"I did do the crime and, you know, I had just come out of high school."
Quesada says she worked in phone customer service and never handled cash.
"We are bound by federal law that generally prohibits us from hiring or continuing the employment of any person who we know has a criminal record involving dishonesty or breach of trust," a spokesman for Wells Fargo told the Milwaukee Journal Sentinel.
Quesada wants her job back, but her termination letter says she's no longer eligible to work at Wells Fargo.
"I think I should get it back because it's something I did 40 years ago," Quesada says. "I paid for it. I've changed my life."
