What not to do when sending appreciation messages for colleagues at work
While expressing gratitude is always a good thing, here are some things to avoid when sending an appreciation note to coworker:
- Don’t just thank someone when you need something. People will notice if you only reach out when you want a favor.
- Don’t be overly generic. A message like “Thanks for everything” is nice but not very memorable. Be specific!
- Don’t make it all about you. Keep the focus on your coworker’s contributions, not your own achievements.
- Don’t forget to follow up. If you thank someone in person or via email, a small follow-up (like a coffee or a handwritten note) can go a long way.
The power of gratitude at work
Taking a moment to thank your coworkers can strengthen your professional relationships, boost morale, and create a more positive workplace. Whether it’s a quick message, a handwritten note, or a small gesture of appreciation, your gratitude will never go unnoticed. So, don’t hesitate—start spreading some workplace kindness today!
