The halo effect occurs when the observer allows the rating of an individual on one trait or characteristic to colour the ratings of other traits or characteristics. A manager might rate a worker as punctual, leading her to give a good evaluation on other factors such as productivity and quality of work. The manager may subsequently rate another worker as frequently late, leading to a poor overall evaluation of the employee's productivity and quality of work. In both cases, the issue of punctuality may be irrelevant to the worker's productivity and quality of work; the employee who is frequently late may actually be the more productive employee.
