Thank-You Letter to a Boss After Your Resignation

A Thank-You Letter to a Boss After Your Resignation is a formal message sent to your employer on the last days of your employment thanking them for the knowledge, experience, and opportunities they shared with you. The letter should highlight how you benefited from their training and how they impacted your professional life.


Everyone you meet during your course of employment forms a crucial part of your professional network, including your boss. When leaving a job, it is essential to leave them with a good impression and feeling about the time they spent with you.

Have you just tended your resignation? Read on to learn how to draft a thank you message for your soon to be ex-boss.

Purpose of this Thank You Letter

You’ve already handed in your resignation, so why not just walk out of the office? A thank you letter to your boss is more than a show of good manners, it also allows you to leave your previous company on good terms. Should you ever need help from your employer, such as with a recommendation, having sent the letter when you left the company can also make it easier to ask.

Structuring Your Letter

A Thank-You Letter to a Boss After Your Resignation is a professional letter, which means it should be structured following a formal business format. The best option is a left-aligned, single-spaced block style letter with one-inch margins on all sides. Once you have the structure right, fill in the following details:

  • Your boss’s address, contact information, and the date
  • A proper and appropriate salutation
  • A reminder about your last day in the company
  • Specific examples of how your boss helped you
  • Gratitude
  • Positive wishes for the future
  • An offer to stay in touch and your contact information
  • A proper closing, your name, and signature

Writing Tips for a Thank You Letter

Drafting this letter after your resignation will be the first time you address your boss as a non-employee. While you may be tempted to write casually, please remember that this is still a formal document. Consider the following writing tips:

  • Provide exact details about your employment and resignation
  • Express genuine gratitude for your boss’s deeds.
  • Mention specific instances when your boss helped you
  • Avoid exaggerating or embellishing the facts as you may sound insincere.

Re: Thank You

Dear Mr. Pritchett

As you know, today marks my last day as a software technician at TTT Solutions as I will be joining RTech Inc. as their new engineering chief. This opportunity would never have come had you not groomed me into the professional I am today and written me a glowing recommendation. I am beyond grateful.

I joined TTT Solutions 7 years ago as a newly-graduated technician with no work experience. Since then, you have taught, inspired, and pushed me to grow in my field. You even allowed me to take time off work to work on my Master’s degree.

I couldn’t be happier that I have your blessing for this new position. I hope we can keep in touch, and if so, you can reach me at

Thank you once again.
