Writing a retirement letter is a professional and courteous way to inform your employer about your decision to retire. The letter should be concise yet appreciative, stating your intention to retire along with the effective date. Begin by addressing your supervisor or HR manager formally and clearly mentioning your retirement decision. Express gratitude for the opportunities, experiences, and support received during your tenure. You may highlight key achievements, positive experiences, or relationships built within the organization. Offer assistance during the transition period, such as training a replacement or completing pending tasks. Ensure the tone remains professional and appreciative, avoiding any negative remarks. If applicable, mention any discussions regarding retirement benefits or exit procedures. Finally, conclude the letter by expressing best wishes for the company’s future and your willingness to stay connected if needed. Keeping the letter clear, respectful, and appreciative will help maintain a positive relationship as you transition into retirement.
