According to the halo effect, a supervisor's initial expectations of you influence your behavior so that you are more likely to act consistently with those expectations.

The halo effect primarily refers to the cognitive bias where our overall impression of a person influences how we feel and think about their character, often leading to a skewing of evaluations based on unrelated qualities. It does not specifically describe the phenomenon where a supervisor's expectations influence an individual's behavior to align with those expectations; that is more closely related to the concept of a self-fulfilling prophecy or the Pygmalion effect.
