Chicago-based Garrett Popcorn Shops is suing one of its former executives accusing them of stealing the company’s secret recipes and other trade secrets. The onetime employee, Aisha Putnam, was the director of research and development for four years before she was fired. The suit claims she had access to the company’s top secret trade secrets. Putnam is accused of downloading company files and saved them on her USB drive and sent it to her personal email account.
