Oh I can relate to this...
Once, it was someone I trained, who attached themselves to me, and then blamed me when unable to perform the job. I put someone else in their place, took them 1:1 through another week of orientation, repeated failures to complete work, inappropriate behaviors, oral warnings, teaching, letters, etc, finally termination----and a 15 page rant about me in return....yikes (it is unnerving...)
Another time, as a nurse, I literally saved someone's life; and by the time I got home, in my head I was somehow at fault for what had happened that had Nothing to do with me....(the things one can conjure up without wanting to!!!)
These things do come and go. But when they are happening, it is hard to imagine the end (diarrhea is usually my thing too....). HUGS!!!!!!!!& glad you have the support of others at work.
(once, a correctional officer, at whose hearing I was to testify, did actually loosen all the lug nuts on my car tire(s)....I did testify, he did know I knew...(someone saw...)---kind of creepy for a while there...but
long ago now...
Gee. I actually work in a safe, positive, nurturing place now....YIKES!!!! (what can go wrong?)
