/nɒnˈ-ˈmændətəriˈ/ – Adjective
Definition: không bắt buộc, tự định đoạt.
A more thorough explanation: “Non-mandatory” refers to something that is not required or compulsory by law or regulation. It indicates that a particular action or requirement is optional or discretionary, rather than obligatory.
Example: Participation in the training program is non-mandatory, but employees are encouraged to attend for professional development.
