Years ago I worked somewhere with a toxic person whose behaviour caused me so much stress that I ended up becoming very ill so I had to leave my job.
I did say at the time that she was the one causing all the stress for everyone else.
I've just had a look at that company's website and apart from the partners I barely recognise anyone's names, but this toxic woman is still there doing the same job.
This really doesn't surprise me at all. Maybe lots of people keep leaving because of her. I'm strangely fascinated. Even one of the long-serving, long-suffering people seem to have finally left.
