Here is my purpose in asking the OP question. Interviewed in Indiana where I was Plant Engineer for Dana Corp. by the R & D Director of Penn Athletic Products Co., in Phoenix, for a position with Penn, Mr. Director asked me if I would object to his verifying my employment history with Dana. After thinking a moment, obviously, such a move on my part would alert Dana to my "looking", so I told him yes, I prefer he would not. We had this interview at a snazzy restaurant in Ft. Wayne the evening after I had toured him through my Plant, to view the automated molding machine (Penn manufactures molded rubber parts: Tennis Balls!) I had co-designed and built.
Next day at the Plant, about noontime, the Personnel Mgr. paged me to her office, where she and our boss, the Plant Manager, had met to demand of me, why some guy called from Phoenix asking for employment information about me! So Mr. Director had LIED to me, straight out! He had not counted on the fact that our plant's management team was crooked as hell! Within a day or so, he called me, and made the job offer; that is how my new wife and I wound up in Phoenix, my new boss starting out in the unenviable position, in my mind, of being a liar, up front! imp
