Very glad I've never used it then! Much prefer my own grammatical errors, plenty I daresay with my old cracked screen.
The woman (Wastenay) sounds like a complete crackpot. Proselytising at work is not on, against all the rules, full stop. She should have known that. I came across similar years ago when I was an HR Manager but it was a one off and not so bad, the person didn't do it again.
Had it been the other way around, the result would have been the same. It's not on, against the rules!
