Many office situations require a thank you note for coworkers. Throwing a party, stepping up at a meeting, and working above and beyond are all reasons for a coworker thank you note. There are some rules you should follow, however, when writing a thank you note for coworkers in your life.
Decide how many thank you notes for coworkers you need. If more than one person helped with a project, you will need multiple thank you notes. Do not address one thank you note to multiple people, as this is considered tacky.
Write the person's name at the top of your card, followed by a comma. The inside should be written in black pen as this looks professional. Under the name, begin a short note about how grateful you are for the service or help that was provided. For example: "Thank you so much for completing the service graphs for our meeting on Friday. You are a lifesaver. I don't know what I would have done without you."
When you have finished your short, three to four sentence thank you note, sign your name below. There is no need for a closing like "Sincerely" or "From." A signature will do.
Deliver your thank you note for coworkers personally. Don't address an envelope. If you work with the individual, you see them often. A hand-delivered note is much more polite.
Some people send thank you notes for thank you notes. Don't do this. It could turn into an endless game.
Don't forget anyone in your thank you note. If you are thanking a committee, be sure to thank every member.
