Is the first impression at work be seen or judged as a halo effect?

Yes it's correct "The first impression at work can be seen or judged as a halo effect". As we observe in our daily life that the halo effect at work in the real world can influence :

How teachers treat students, but it can also impact how students perceive teachers. In one study, researchers found that when an instructor was viewed as warm and friendly, students also rated him as more attractive, appealing, and likeable.

Marketers take advantage of the halo effect to sell products and services. When a celebrity spokesperson endorses a particular item, our positive evaluations of that individual can spread to our perceptions of the product itself.

Job applicants are also likely to feel the impact of the halo effect. If a prospective employer views the applicant as attractive or likeable, they are more likely to also rate the individual as intelligent, competent, and qualified.

So, the next time you trying to make an evaluation of another person, whether it is deciding which political candidate to vote for or which movie to see on a Friday night, consider how your overall impressions of an individual might influence your evaluations of other characteristics. Does your impression of a candidate being a good public speaker lead you to feel that she is also smart, kind, and hard-working? Does thinking that a particular actor is good-looking also lead you to think that he is also a compelling actor?

Being aware of the halo effect, however, does not make it easy to avoid its influence on our perceptions and decisions.

First impressions are more heavily influenced by nonverbal cues than verbal cues. while usually people pick up your attitude instantly. Before you turn to greet someone, or enter the boardroom, or step onstage to make a presentation, think about the situation and make a conscious choice about the attitude you want to embody.
