Yeah I have to say I also disagree. I'm EE, 20+ years of "professional" experience and I would never use the the term "Professional Engineer" to describe myself and I don't ever recall any collegues using that term who were not licensed. Pretty much every Engineer I know understands the difference and would never use the term. It's like saying you are a lawyer when you haven't passed the bar. In fact within the industry you would typically refer to those people as a "PE" (even if they were Civil, Mechanical or Electrtical in training). Of course it is totally fine to use the term professional in a descriptive manner, i.e. "We expect you to act in a professional manner when speaking with the customer". Of course this is only an American thing as far as I know, I have no idea what the practice would be in say Australia.
