I’ve had the luck to hear Levitt speak on a couple occasions, including a debate which included the president of the union I worked for, Levitt, and a couple of current union busting attorneys. While some of the tactics may have changed, the underlining method of attack is still the same. Unfortunately, there are not as many of these videos as I had hoped, but I did find a collection so you can hear his words yourself. I’ve also included a link to Levitt’s book (Which I had loaned out and never got back) The book is a fascinating look into anti union tactics.It is cheaper than the link says if you buy a used copy. Just click through to see the prices.
