I attended a presentation today at the 29th Labor & Employment Law Section Annual Conference where Andrew Friedman of Helmer Friedman in Venice, CA, was one of the speakers. Mr. Friedman typically represents employees in employment disputes; however, he previously worked for a prestigious employment defense firm, so he has a very grounded ability to look at discrimination cases from both sides–which is a skill required by workplace investigators. I had the opportunity to look through his book Litigating Employment Discrimination Cases, which is written for both plaintiffs and management lawyers.
I highly recommend it for workplace investigators as well.
