Those are really American though.. like "co-worker", that isn't a word which was used in England. We'd use "colleague". It came from American English as part of the corporate lingo.
This particular case may not be a good example, but Brits tend to forget that they actually invented some of the words that they blame Americans for. Soccer is a perfect example, though I think the "Lost in the Pond" YouTube channel has a video or three with several more.
