This has been a huge problem where I work. I have turned in 3 companies in the last 6 months. I live in a small community of 15,000 people and if it's this common here then in larger communities it must be worse. All of the companies i turned in had never been members and were never Certified at any point and yet they were claiming to be certified on their websites,phonebooks, and trucks. ISA took swift action and I can report that the website and truck logos have been removed. The phonebooks were already printed so those ads will have the logo for another year which chaps me!
We have to police this ourselves, protect our credentials, and our investment in ISA!
