For the PIP guy - maybe you did bust your backside, but maybe you also made everyone else's life miserable by going on and on and on about how very hard you were working and how everyone else slacks off/takes advantage/is incompetent.  We had one of that type of hard worker at my workplace and they finally got counseled and the equivalent of a PIP and both they and the rest of us are getting along much better!  And yes, the management also improved their "attaboy" thank-you skills!
