Neither do I. I have been there since 2014. I have only been coached once during that time. I rarely call out. I show up on time. And I have been TM of the Month a couple of times. Yet, I have never gotten a DEO. Furthermore, I am a trainer for the Front End. If I'm doing something wrong, they better damn well tell me before I pass something along to a newbie.
I think my real reason for griping is I usually ask what I can do to improve in an area they marked me low in and the GSTL will say something like "Well, I don't really think you deserve this score" or "Meh, everyone needs a little improvement in this area" and can't give me an answer. Why would I sign for that?
