It’s important to thank colleagues who help you out at work. They need to hear that their efforts are appreciated, and that you are willing to reciprocate when you can. Sending a formal written thank you note when someone helps you at work is not only polite; it also serves to strengthen your relationship, heighten camaraderie, and build positive morale in the workplace.

When writing a thank you letter to a coworker, it’s fine to keep the tone casual, as long as your format is correct.

You can send a thoughtful handwritten note, if you feel that it would be well received, or an email.

Use a professional salutation and closing. In your note, specify exactly what it was you appreciated and how the person’s input was beneficial to you or to a project you worked on together. You should also offer to help them in the future if you can. Use first names if you do so in person, and always make sure you proofread for spelling and grammar.

To add even more value to your thank you email or letter, it’s a nice idea to send a carbon copy (“CC”) to your helper’s supervisor; for an email message, simply insert the supervisor’s address in the CC field. This helps to raise awareness among the “powers that be” of how important an asset your colleague is to the organization as a whole.

Here are some sample thank you letters to send or email to a colleague.
