Step 1: Make sure you have a case before you file a lawsuit.

The Chronicle of Higher Education reports:
"The University of Notre Dame, defending itself in a lawsuit over its decision to fire a tenured engineering professor, Oliver M. Collins, has asserted in court documents that Mr. Collins used more than $190,000 in research grant money and university resources to buy unauthorized equipment, including digital cameras he used to take pornographic pictures."

A commenter on the Chronicle's blog summed it up nicely:
"If you're going to sue your employer for wrongful termination you need to be aware that the employer's defense will become public information. What was this guy thinking?"
