John Stone, 34, says he wore a Packers tie to work on Monday to honor his late grandmother who died earlier this month. She was a big Packers fan.
But his bosses at Webb Chevorlet in Oak Lawn say the company has promotional ties with the Bears and they didn't want the tie to upset customers. Stone refused to take off the tie, so he was fired.
On Wednesday, Stone said he has received a lot of support.
"More support than criticism. There's always going to be somebody to criticize, but the support has been overwhelming, and they have my back because it's not right. You don't get fired over a tie," said Stone.
Webb Chevrolet offered stone his job back but he declined.
Stone begins his new job at Homewood Chevrolet on Thursday.
