Night,
Man this is too weird. I just went thru the same thing 2 years agao and left my company for many reasons.
1) I had alot of anger built up and things were not right at my company so i built a case and decided to leave.
2) I went thru my exit interview and i unloaded proffesionally and went fromthe top to the bottom of the things wrong, safety issues and many many more things.
3) Went off to my new job and i was not making the money i was at the other place. 3 months later i was talkig to my old supervisor that was cool as hell and he asked if i would come back. I told him sure. well they had a meeting and all said i burned my bridge. I callled the plant manager and asked the reasoning for me not being considered for re-employment and he said, "we had issues with your exit interview". I asked what those issues were and he would not answer me, i was told that in no way would this be against me if i were to try to come back, it did! The plant manager asked for another meeting and said he would really like me to come back and voted me back in. I started 2 weeks later. So in my opinion, do your exit interview, be stern, but be catious in what you say. You might end up like me, back at the place.
