Answer:
social sanction
Explanation:
According to my research on studies conducted by various sociologists, I can say that based on the information provided within the question the glare is an example of an informal social sanction. This term refers to any action or behavior indicating to another individual that they have done something wrong, which can include a glare, scowl, shame, ridicule, sarcasm etc. In this situation the executive glared at Jennifer indicating to her that she messed up and that he is upset.
