It’s 6 p.m. on a Friday. Just as you finish packing up for the day, an email from your boss pops up on your phone asking why an urgent payment didn’t go out earlier in the week. He’s tied up in a business dinner, so he needs you to wire payment to a specific vendor immediately and send him a confirmation email here once you’ve done so. Eager to help (and get out of the office for the weekend) you transfer the money and email your boss. He thanks you for going above and beyond.

Come Monday morning, you’re pulled into an emergency meeting. The company has lost $157,000.
