What is the term for the duration an employee must notify their employer before leaving a job?

The term used to describe the duration an employee must notify their employer before leaving a job is known as the notice period. This period is significant in employment relationships as it ensures that both the employee and employer have time to prepare for the transition. The employee provides advance notice, which allows the employer to make necessary arrangements, such as finding a replacement or reallocating responsibilities. A notice period can vary depending on the company's policies, the employee's contract, or applicable labor laws. This concept is rooted in the principles of professional courtesy and contractual obligations, ensuring a smoother transition for both parties involved.

The other terms listed do not accurately define this concept: the resignation period refers more generally to the act of resigning rather than the specific timeline; contract duration pertains to the length of the employment agreement rather than the notice requirement; and termination period typically refers to the context of ending employment rather than the advance notice required prior to departure.
