My proof is 38 years of practice, handling multiple employment cases in litigation, generally representing financial institutions, the insurance, securities and transportation industries.  Opposing parties were generally highly compensated individuals.  Yes, there were sometimes allegations of misconduct involved, occasionally egregious in nature.  All were represented.  Less often, I represented individuals whose former employers wished to restrain them from competing.

Settlement inevitably included negotiation over the topics I described.  You conclude my comments are "spurious," "unwarranted," "misleading" and "not true," this after asserting without proof in your article that employers resort to NDAs only out of the most nefarious of motives.  My lifetime in litigation would indicate otherwise.  I believe you have attributed ugly motivation and conduct to good people you don't know.
