Which of the following applies to a resignation expressed in written communication?

A resignation expressed in written communication is classified as a formal resignation. This type of resignation typically involves the employee providing a clear, written notification to the employer, indicating their intention to leave the organization. The formal nature of this communication ensures that there is a documented record of the resignation, which can help prevent misunderstandings and clarify the employee's last working day, intentions, and any transitions needed.

Written resignations are generally more accepted and respected within professional settings, reflecting a level of seriousness and professionalism from the employee. By contrast, other options like informal or unformal resignations generally imply a lack of structure or a casual approach to leaving a job, which may not provide the same level of clarity or commitment.
