Have you ever felt like although you have been in your position for a few years, and in the business for more than that, your boss continues to talk to you like you don't know anything? That's the TALK DOWN. Feels awful, like you are stupid.
Fortunately that is not the case - it's the boss - they do not understand their audience. They speak as if everyone is a beginner. This could be for many reasons - they are insecure about their position, they do not know their material (or what they are talking about) well enough, they do not trust their team (a whole other blog topic) or they are insensitive and plain, just don't get what it is to be a leader.
What to do? Remind the boss that although you appreciate the reminders, you have been in position for a good while and hope that they will soon trust you and your judgement. Explain how it makes you feel. Sometimes they just need to be told.
