I've noticed supermarkets and places like Argos referring to the people who work in their shops as "colleagues", not as if they are talking about their own colleagues, but as if that is the word for them for all of us.
So they will say things like "if you need help, find a colleague and ask them" - none of my colleagues are usually there as I usually only see them at my place of work.
Why and when did they decide to change the use of a word in the English language that the rest of us were already using for something else?
AIBU to think this isn't the way to use that word?
