I think I am about to..
I had a minor injury at work (equivalent to a paper cut) on the evening of the event I posted a picture of on FB in a self depricating manner and thanked those who saved my life with rapid action (ie the first aid box was opened and a small plaster was applied).
Later I had an email from our safety officer asking me to take it down. I had mentioned that I had done it at work (not the name of work or anythign like that). On FB where I work is not listed as I like to be a bit private. I realsied he can see it because I tagged a friend, otherwise my privacy is limited to firends only, not friends of friends.
Anyway I have now changed the privacy settings so he can’t see it, but I know that he has already asked a friend if it is still there.
If it goes anywhere I am going to just hand my notice in.
