What is the most common way individuals notify their employer of resignation?

The most common way individuals notify their employer of resignation is through a letter of resignation. This method is preferred because it provides a formal and documented way of communicating the decision to leave the organization. A resignation letter typically includes the employee's intention to resign, the last working day, and expressions of gratitude towards the employer for the opportunities provided during their tenure. This written communication creates a clear record that can be referred to later, ensuring both parties are on the same page regarding the terms of the employee's departure.

While email notifications, phone calls, and in-person conversations are also used, they can lack the formal nature and documentation that a letter provides. Email may not carry the same level of professionalism as a letter, a phone call may be less formal and could leave room for misunderstandings, and in-person conversations, while direct, may not always allow for a documented record unless followed up by a written communication. Thus, a letter of resignation stands out as the most common and accepted practice across many industries when formally notifying an employer of resignation.
