A "yes-person" is someone who always agrees with others, even if it means sacrificing their own opinions and beliefs. Such a person is sometimes referred to as a "pushover," "doormat," or "people-pleaser." Other synonyms for a "yes-person" include "sycophant," "flatterer," "brown-noser," "toady," and "bootlicker." These terms usually have a negative connotation because they imply that the person lacks independence and spine. In contrast, someone who is assertive and confident in their own ideas and values is more likely to be respected and admired. Ultimately, being a "yes-person" can be detrimental to one's personal and professional growth and success.
