While out on FMLA - I was moved to a different team and a different cube, my stuff was haphazardly thrown into a box, and my manager quit.
I came back to no desk, no boss (it's been 5 months and this is still the case), and some broken personal effects. Oh, And someone swiped my yoga ball. My end-of-year review was basically my (former) boss's boss asking me, "so what do you do?" I've been busting my butt, but no one I reported to last year was here to vouch.
