Catherine, a RN, was unhappy with her job, so she submitted her resignation. She was sure she'd have no trouble finding a new position, because of the nursing shortage in her area.

She e-mailed cover letters to dozens of potential employers and attached her resume to each one. Two weeks later, Catherine was dismayed and bewildered that she had not received even one request for an interview.

Finally she received a message from a prospective employer that explained the reason she hadn't heard from anyone else.

It read: "Your resume was not attached as stated. I do, however, want to thank you for the vegetable lasagna recipe."
