Answer:
Sheng thought that it would be a violation of cultural orientation
Explanation:
Cultural oreintation is an inclination to think, and act in a certain way that is culturally acceptable in a particular place. For example, in most African and Asian part of the world, it is a culturally acceptable standard to address your elderly ones in formal settings like Elder sister of elder brother. This is a form of respect and acknowledgement of age differences among the individals involved.
Doing so, shows the cultural upbringing of the person unlike in United States where it is common to address people by their first name. In the case of Sheng, she believes that, a situation where their boss is addressed by first name shows a violation of cultural orientation which has been inculcated in her while growing.
