I have a feeling this form is exactly the same one as everyone signs. It's not an NDA as most think. It's the "I won't share company secrets or bash the company on social networks or speak to the media".... Blah blah blah. HR has it so they can use it if you go "CA Insaneo" down the line.

New hires aren't getting anything "juicy" that they gotta keep quiet. Keep in mind, for many new hires, this is their first job outside of the university instructor job... Perspective.
