According to always reliable internet statistics, 75% of employees have stolen from an employer at least once in their life.
As a guy who always enjoyed drinking free beer with his fellow servers after we closed Applebee's for the night, and has recently noticed an eBay account called CómpraloYa69 selling Lost Ogle ink pens for pennies on the dollar, that sounds about right.
In fact, employer theft is so common that even the Oklahoma City Zoo has fallen victim to it. Earlier this week, news reports came out that an entrepreneurial now ex-employee named Joshua Lucas was stealing baby tortoise hatchlings and selling them to a dude in Las Vegas.
