Simon that behaviour goes well beyond a simple annoyance. Nobody should have to put up with that.
I’ve got colleagues who don’t do my job and have absolutely no idea how to do my job, but still feel that their contribution is required when I’m discussing a technical aspect with someone who does actually understand what I’m talking about. And when politely told that their suggestion won’t work, demands an explanation (which they also won’t understand) why not.
I work with Foghorn Leghorn who has no volume and goes from desk to desk, repeating the same, incredibly boring story again and again. By the time they get down to my end of the office, I’ve heard it 26 times already.
I also work with the ultimate mansplainer who has opinions on everything from childbirth to leg waxing and who loves to share his expertise.
I love weekends.
