The executive has blocked my wife from getting promoted because of his dependency on her. Oh she could leave but she is not in the tech industry so its not like jobs are all over the place.
The worse part is that her taking the role many years ago was in large part my faulty recommendation as I thought being closer to the money would allow for greater compensation (which it did but was not worth it).
Email to someone. Suggest meeting.
Someone's email, CC you: assistant, schedule this.
Email to assistant. Let me see when X is free (cc you, person).
Person's reply to everyone, you and assistant: tell so and so, let's do X at 2pm.
Assistant's email (cc you, the person you were talking to): we'll do X at 2pm.
I think somewhat the same about why travel agents are dying out, having to tell them exactly what flights you prefer and where, and how to not screw up your layover (and be able to easily reschedule when they are not around), it's usually far faster to just do it yourself.
So it ends up being more about having a status symbol.
