'待遇' (dài yù) literally combines '待' (to treat, to receive) and '遇' (to encounter, to meet), together meaning the way a person or group is treated—especially in terms of fairness, respect, privileges, or material benefits. It often implies a formal or institutional standard of treatment, such as that provided by employers, governments, or social systems.

The word carries a subtle evaluative tone: 'good treatment' (好待遇) suggests favorable conditions like salary, housing, or leave policies, while 'poor treatment' (待遇差) signals disadvantage or discrimination. It’s commonly used in workplace, education, healthcare, and policy discussions—not for casual interpersonal interactions (e.g., you wouldn’t say '他对我待遇很好' to mean 'he treats me nicely'). It functions exclusively as a noun and is rarely used in verb phrases.
