What is a resignation letter due to illness?

A resignation letter due to illness is a formal notification that you’re leaving your job because of health reasons. It communicates your decision to your employer and explains, in as much detail as you’re comfortable with, the health-related reasons behind it. The letter helps to ensure a smooth transition and allows your employer to prepare for your departure while showing respect for your professional relationship. It’s a key step in closing out your current employment on good terms, without burning bridges, so you can focus on your health.

Understanding your legal rights when resigning due to illness

Submitting your resignation letter is not just about notifying your employer of your departure; it also opens the door to important discussions regarding your rights and benefits. This conversation can explore whether you qualify for certain entitlements and, if you’re open to returning, whether your position can be available to you in the future. It’s essential to educate yourself on these aspects to make certain you’re fully aware of your options and rights as you transition out of your role.

When resigning due to illness, it’s crucial to be aware of your legal rights and potential entitlements, which can differ based on your location and specific situation. Key considerations include whether you’re eligible for retirement benefits, unemployment benefits, continuation of health insurance, or medical leave.

How to write a resignation letter due to illness

Your resignation letter should follow the same format as any other business letter. Here’s what should be included:

  • Date: Start with the date at the top of your letter. This documents when the letter was written and can be important for notice periods and other time-sensitive considerations.
  • Address: Address the letter to the appropriate person, such as your direct manager or the HR department. Include their title and company name for formality.
  • Salutation: A formal greeting, usually something like “Dear [Manager’s Name]”
  • Statement of Resignation: Early in the letter, clearly state that you are resigning from your position. It’s straightforward and respectful to mention this upfront.
  • Reason for Resignation: Briefly explain that you are resigning due to health reasons. You don’t have to go into detail about your illness if you’re not comfortable doing so.
  • Notice Period: Mention your last working day, adhering to any notice period requirements in your contract. If you’re uncertain about how much notice to give due to your illness, you can express willingness to discuss a suitable end date.
  • Offer to Assist With the Transition: If you’re able, offer to help with the transition process. This could include training replacements, wrapping up projects, or documenting your work.
  • Appreciation: Express gratitude for the opportunity the company has given you and for the experiences you’ve had. This helps to leave on a positive note.
  • Closing: End with a formal closing, such as “Sincerely,” followed by your name and signature (if sending a hard copy).
  • Contact Information: Optionally, you can include your contact information below your signature so your employer can contact you in the future if needed.

This structure ensures that your resignation letter is professional, respectful, and clear, providing all the necessary information to your employer while also respecting your privacy regarding personal health matters.

Tips for maintaining professionalism in your resignation letter

Maintaining professionalism in your resignation letter is key to leaving on good terms. Here are some tips to help ensure that your letter reflects professionalism:

  • Keep a formal tone; avoid using colloquial language, slang, or making jokes
  • Open and close the letter with a professional greeting and sign-off
  • Address your employer by their appropriate title
  • Avoid overexplaining your circumstances, and aim to keep the letter concise
  • Proofread your letter to avoid making any grammar, spelling, or punctuation mistakes. Grammarly can help you check your letter for concision, tone, and grammatical errors so that your letter is mistake-free and your message can be easily understood.
