Steve, I found various polls and estimates on what percent of employees steal, which seems to vary based on sector and type of theft (e.g., food vs. cash). The California Restuarant Association estimates 75%, the American Polygraph Association estimates 50%, the FBI estimates 70%, and the Justice Department estimates 30%. Us "Never Steal" types ARE a minority.
Wow, this data makes me sad, but I guess even if an employee 'forgot to return' some stationery from the office it could also be counted as 'stealing'? This may be why there is a large variety in the percentage.
