As I've got older and more experienced, I've noticed a definite increase in the number of people in leadership roles feeling the need to explain things to me veeerrry simply and clearly. It happens most when said boss is the same age or younger than me. I don't count it as 'mansplaining' because although the perpetrators tend to be male, I've seen them do it to men as well as women.
Here's a typical example. I work in a marketing consultancy with mostly tech-related clients. The job involves hopping around from topic to topic, needing to reach a reasonable level of understanding of a variety of different industries relatively quickly. We also need to understand generally what's going on in the world / the economy / politics etc.
Some of us have been doing this for many years. We have learnt things. We read newspapers. We do not live under rocks. And yet some people - especially our MD - LOVES carefully explaining things that we already understand. And not always correctly.
It used to happen in my previous company too. Same basic scenario, only in this case the MD would also carefully explain 'complex' topics to his own (equal) business partner in briefings. The partner is a good five years older, and is a very smart, experienced, well respected guy.
I've even had my own presentation boss-splained back to me. (Slowly of course.)
Do MDs feel so uncomfortable around more experienced people that they feel the need to play a game of 'I'm the clever one' ??
Anyone else think this is a thing? Makes me cringe.
