When interviewing for a job, it’s standard procedure to send a thank you note after the interview. However, what about when you have the job? How can you thank that coworker who helps you out of a tough spot right before a deadline? Should you even send a thank you note to a colleague?

Occasions to Consider Writing a Thank You Note

The answer is yes! A coworker might not expect a thank you note, but getting one might just make their day. It’s polite and thoughtful to thank someone for what they do, especially when it’s to your benefit. Here is a list of reasons you might consider sending a thank you note to a coworker:

  • Covering a shift in an emergency
  • Helping out with a project
  • Volunteering to help you meet a deadline
  • Mentoring you through a project or new job
  • Leaving the company (or you are leaving the company)
  • Providing a recommendation
  • Recommending you for a promotion
  • Generally supporting you in the workplace

Whether it’s one reason or another, your coworker will appreciate a personalized thank you note. It’s a professional and personal way to express your gratitude for their help in the office, making your workday a little easier.

Thank You Notes: Handwritten Cards or Emails?

If you realize that a thank you note is in order, the next question becomes: how do you go about writing it? You can send a quick email or write a handwritten note to express your gratitude to your coworker.

Emails are more professional than handwritten cards and are usually easier to write. If you need to tell your coworker thank you quickly and efficiently, or you don’t know them very well, an email is the best way to go.

While emails are professional and quick, handwritten notes are much more personal. There are many ways to go about writing a handwritten note to a colleague–you can buy fancy stationery and leave a note on their desk, or you can jot down a heartfelt thank you note on an index card.

While you can type up a letter and print it off, this might not be the best idea for a quick thank you note for a coworker. A typed letter is exceptionally formal and might not leave the right impression.

Whether you choose to write a thank you note by hand or send an email, your coworker will appreciate the time you took to thank them. Handwritten notes tend to create a longer-lasting impression. Remember, it’s the thought that counts.
