How to Show Genuine Appreciation to a Coworker or Colleague (Plus 44 Sample Messages)

Before you write that note, consider what specifically you’re thanking your coworker for. Did they streamline a tricky project, help onboard a new hire, or just keep everyone calm during a chaotic week? Pinpointing the exact reason makes your appreciation more sincere.

• Avoid vague praise: “great job” can feel hollow. A short note about how their action made a difference feels far more authentic.
• Zero in on specifics: mention the project, skill, or moment that prompted your thanks.
• Show how it helped: clarify the positive ripple effect—did they free up your schedule, boost team morale, or solve a backlog?

While some colleagues might appreciate a public shout-out, others may prefer a discreet note. Think about how each person prefers to be recognized and match your approach accordingly.

• Public vs. private: a group announcement can motivate the entire team, but a personal card might resonate more with a shy coworker.
• Timing: if someone just wrapped up a demanding phase, catching them right after can be extra meaningful.
• Length: a few genuine lines often hold more weight than a rambling paragraph. Keep it tight, warm, and to the point.
