I had to check what ghosting means

I don't think it will hurt, although the cases I'm referring to are not related to ghosting, if I understand correctly?

Let me give examples:

1. We are periodically tormented by an alarm that goes on when someone leaves the door open (and the alarm is louder inside our room than near the door). I e-mail one of the directors and she ignores me. Twice.

2. I am given an annual appraisal of 1/5 which is extremely unfair and provokes serious damage, both in my professional and personal life. I ask for the help/support of another director by e-mail, which simply ignores it.

These are maybe two of the most notorious examples.
