How to Personalize Your Work Anniversary Message

Sharing how much you value your coworker is a great way to celebrate their anniversary. To show your genuine appreciation, you may want to add a personalized touch to your anniversary message.

Keep these tips in mind:

  • Include specific accomplishments, progress, and personal growth. Consider times the receiver overcame difficulties, led an important project, or improved their skills in a certain area. Anything that’s set them apart in the workplace during their time with the company may be worth mentioning.
  • Consider their personality. If the receiver is a jokester, put a humorous spin on your message by including a joke or work-related pun. If they’re the serious type, keep it strictly professional. Whatever their personality, use a similar tone when crafting your message.
  • Take inspiration from their favorite things. It’s hard to go wrong when mentioning the receiver’s favorite things. This could be their family, pets, hobbies, hometown, or anything that makes them light up to talk about.
