Also, it’s not like she doesn’t explain what it is. It’s that she doesn’t explain why the deadline is tight.
We had one project in particular where there was a tight deadline and I did ask why as it wasn’t clear. She said “when I get a deadline from Bob (president of company) am I supposed to ask him why and if we can push it?”
That was telling to me. She doesn’t ask why/her boss hasn’t been working with her on when things are due. I don’t think she should all the time but if it seems absurd, I do think she should ask or push on a deadline personally. All the deadlines that exist Don’t come from him though.
