A guy I worked with was fired for sending this to a woman we worked with that he had a grudge against for some reason or another. Apparently he sent it from his work computer, which wasn’t the brightest idea. He sat in the next cube over from me and I wasn’t surprised in the slightest when I heard about it.
I've had to let a few reports go for inappropriate statements. Without exception, whatever they got in trouble for saying they prefaced with "I probably shouldn't say this, but..."
For the love of God if you can put that into words just don't say whatever the thing in question was
