Not to wind you up but…
My partner replied to a mail from a colleague in which he stated some external contractors sometimes act like cowboys. The so-called-colleague forwarded this mail (with a throw-away line in it, not the main thrust of the mail or owt) to the third party who then got in a huff.
The short of it was a disciplinary followed by a written warning (nothing happened to the colleague who sent the mail externally, of course). Then, lo and behold, shortly after this there was an email to all staff to discuss redundancies. “Oh look AdamW’s better half, you have a black mark here due to a disciplinary. Don’t slam the door on the way out, and it is statutory redundancy.”
Yes, he shouldn’t have written what was a throwaway line to someone he thought was a colleague. Now he’s scared stiff that he won’t get another job because of the disciplinary that happened beforehand….
BUT
I think you’ll be all-right. If it is internal type stuff it would, at the most be a word in your ear.
