At one of my previous jobs it was the head of HR stealing people’s food. Every time somebody complained he’d put up a sign and start “investigating”, but nothing ever came of it despite having cameras pointed at the fridge. Eventually someone got tired of it, put up their own camera, and caught the head of HR on camera a couple times. Apparently the president of the company didn’t care and brushed it off. I only found out because the guy with evidence blanket emailed the videos to the whole company. Of course he got written up for doing that.
