You are not alone in enjoying praise and acknowledgment — everyone craves positive attention, including your boss. So when your manager does something particularly helpful or meaningful, take the time to say thank you with a letter of appreciation. It's the nice, polite thing to do, and most likely, your boss will appreciate the gesture.

When Is It Appropriate to Send a Letter of Appreciation?

There are a few different reasons you may feel compelled to send a letter of appreciation, including when your boss:

  • Lends a hand: If your manager offers you resources or help to solve a problem (e.g., a part-time staffer to help on a project, a new piece of technology, or even a joint brainstorming session).
  • Does a personal favor: Maybe your boss allows you extra leave time or is understanding with days off, even though you're taking them during a busy season. Or perhaps your boss connects you with someone in your field who can help further your career, or takes some time to provide you with personal mentorship or advice. 
  • Gives you a promotion, raise, or bonus: While the extra money or promotion comes from the company's coffers, most likely your boss has been instrumental in some way in recommending that you receive it.
  • Provides an opportunity for advancement: It's not only a raise or promotion that deserves appreciation; your boss sets you up for those measures of success by funneling important projects and initiatives in your direction. Without that trust in your abilities, it's harder to show off your talents.
  • Coordinates a collection for you or a family member: It isn’t unusual for good bosses to “pass the hat” for contributions when an employee experiences either a happy personal event (such as the birth of a child, a wedding, or a graduation) or a sad transition (like the death of a family member). When this happens, it is more than appropriate to send a thank-you note to your boss, along with a request that he or she pass your thanks on to all of those who contributed.
  • Announces that he or she is leaving either your division or the company: If your boss announces that they are leaving your division (through promotion or reassignment) or is leaving your employer (because of retirement, a new job, or a layoff), this is a wonderful time to write a sincere note that expresses your gratitude for the things they have done for you. Remember to wish them success in their new endeavors.

Similarly, you may want to send your boss a letter of appreciation when you yourself leave the department, or if you leave the company entirely.

Tips for Writing 

Of course, when you are writing to your boss to express gratitude and appreciation, you have to be careful with your tone. You want to make sure you appear sincere — and not like a sycophant.

In your letter, mention why you're writing and provide a specific thank you. Include a complimentary close at the end of your letter, before your name. 

Here is a sample appreciation letter to send or email to your boss.
