Answer:
The "glass ceiling"
Step-by-step explanation:
The glass ceiling is an artificial barrier that prevents minorities and women to promote to the managerial and the executive level.
The glass ceiling effects show that how much difficulties have been faced by women when they trying to prove themselves in male dominating societies.
This barrier mostly invisible, not in written language. The women are restricted by the accepted by norms and the implicit biased rather than defined corporate policies.
Agatha's lack of promotion most likely illustrates the glass ceiling effect.
