Just as you would send a friend a thank-you note or email for lending a hand or doing you a favor, it's also a kind gesture to send a quick note to colleagues who help with something work-related.
Whether it's a coworker or someone you manage, a note of appreciation is always welcome. Your thank-you note does not need to be formal or lengthy—just make sure it includes your gratitude.
If you want to do something extra special—and if it's appropriate in your company—you can copy the person's manager on the note or email.
That way, the manager (who most likely has the power to give raises, bonuses, and promotions) is aware of your colleague's help as well.
How to Write Your Thank-You Note
Depending on the circumstances, you might want to send a letter, card, or note by mail to thank your colleague for the help he or she gave you on a project. This can be a nice touch.
A card to put on a bulletin board or desk is a lasting reminder of appreciation, and also serves as a hard copy record for the person's files. If you are handwriting your note, remember to include the date on the top right side of the note.
Email is also a perfectly fine way to express appreciation. However you decide to send your thanks, your letter will contain the same elements.
What to Include
You should begin with a salutation. Depending on your relationship, you might choose “Dear” or “Hi” since this is an informal note between colleagues. As in all business correspondence, don’t use abbreviations or slang. The note can be informal, but all work-related correspondence needs to maintain a professional tone.
Body of Email or Note
The body of your letter should mention a few ways that the person's expertise was valuable to your project—you can mention how much you appreciate the time the person took out of his or her busy schedule to offer assistance.
In your closing, it’s always nice if you can offer to reciprocate in some way. Otherwise, you can just share your gratitude and pleasure about having the opportunity to work with the person on this particular project.
Then end your letter with a complimentary close, followed by your signature.
Sample Thank-You Emails
Here are sample email messages or letters that thank an employee for help with a project. Use these examples as a guideline when creating your own letter or message, and include specific details about how the person helped out.
Thank-You Letter for Help With a Project #1
Subject: Thank You
Thank you very much for offering your assistance on the upcoming Human Resources project. I really appreciate your willingness to help out outside your current position.
It is helpful to have someone who has had experience with similar issues on previous projects to offer guidance and direction. I know HR is happy to have you assisting in this matter.
Let me know if you need anything from me. I can make someone available to help your team out while you spend a few days with the Human Resources staff.
Sample Thank-You Letter for Help With a Project #2
Subject: Thanks for Your Assistance!
I wanted to thank you for taking time from your busy schedule to help the Finance department get the year-end accounting completed.
I know the work wasn’t part of your normal responsibilities, but your assistance was invaluable in helping my department get everything done in a very timely manner.
Your expertise and enthusiasm were both appreciated during a time which can be stressful for all concerned!
We sincerely appreciate your efforts and thank your manager as well for sharing some of your schedule with the Finance department.
