The phrase "give notice" is commonly used in employment and contractual contexts to describe the formal act of informing another party that an agreement or working relationship will end or change. In the workplace, it usually means that an employee officially tells their employer they intend to leave their job, often respecting a required notice period. It can also refer to an employer formally informing an employee that their employment will end. More broadly, it can mean providing official advance warning of an action, change, or event, typically in writing and within a specified time frame.
