What is the best way for an employee to inform an employer of resignation?

Writing a letter of resignation is the best way for an employee to inform an employer of their resignation because it provides a formal and professional manner of communicating this important decision. A letter offers a clear record of the resignation, including the date of the last working day, which can help both the employee and employer transition smoothly.

This written document can be retained for company records and can also serve as a reference for the employee’s future employment. It shows respect for the employer and acknowledges the employee's time at the organization. Additionally, a letter of resignation typically follows certain etiquette in the workplace, reinforcing a positive professional relationship.

Other methods, such as verbal discussions or emails, might be effective in various contexts but lack the formality and documentation that a letter provides. Text messages, while quick and convenient, are typically considered informal and may not convey the seriousness of the decision.
