Thanks FF.
Yup: invented incidents, now at least one per flying flying day. Threat, abuse, insane allegations and all broadcast by e mail. I looked it up on the internet, it's work-place bullying, usually aimed at the most experienced troops because they pose the biggest threat (inexperienced dullards cause no trouble).
Bloke's trying to hang on to a well paying job by discrediting people who've been around for years and know the traps.
Anyway, it's terribly libellous indeed, and all is on record.
Thanks for your input.
