Instead, Bowden said, her supervisor placed her on leave — and on Monday, Bowden received a registered letter from the Pocatello/Chubbuck School District informing her she had officially been fired for theft of school property, according to the Idaho Statesman.
"My heart hurts. I truly loved my job, and I can't say that I wouldn't do it again," Bowden, who worked in the school cafeteria for three years, told the station.
Her firing has sparked outrage on social media. A petition calling for her job to be reinstated had more than 48,000 signatures as of Wednesday afternoon.

But Bowden said if a child exceeds the $11 credit limit, workers are instructed to take their tray away and throw out the food.
Study after study has found that hungry children perform worse at school. According to the National Education Association, missing meals affect a child's academic performance and behavior in school, and hungry children are more likely to repeat a grade, be tardy for school, or miss school.
