Before employees begin leave for jury duty, ask them to show you a summons or other proof of service. Don't just take their word for it. Why the formality? Case in point: A Miami-Dade County Clerk's office worker was arrested recently for falsely claiming that he served on federal jury duty for six months. He collected $17,388 in pay during his time away. The court originally summoned the man for one day, but then didn't need him. Still, he continued his lie for six months until his employer finally asked for proof. He quickly resigned, and when the employer checked with the courthouse, it discovered that he never served on a jury at all.
