/tə saɪn ˈʌndər ˈprəʊˌtɛst/ – Phrase
Definition: ký vào bản kháng nghị.
A more thorough explanation: “To sign under protest” refers to a situation where a person signs a document or agreement, but explicitly states that they are doing so unwillingly or under duress, and that they do not agree with the terms or contents of the document. This action allows the individual to challenge the validity of the document or agreement at a later time while still acknowledging receipt or presence.
Example: The customer agreed to sign the contract under protest, indicating that they were signing it against their will but acknowledging that they had no choice in the matter.
