How to write farewell messages for your coworker
A work card should be warm and professional at the same time. Mention something real: the project you got through together, the way they help new people, the snacks they leave on the shared desk. Keep it friendly and positive, avoid anything too personal, and don't joke about their age or salary. If several people are signing, keep your line short so everyone fits.
A farewell message mixes a little sadness with a lot of good wishes. Say you'll miss them, thank them for something specific, and wish them luck in what comes next. For a colleague, that might be the help they gave or the fun they brought to the office. For a friend moving away, it's a promise to stay in touch.
Keep the focus on them and their new adventure, not on how hard the goodbye is for you. And leave the door open: "Let's still grab lunch" or "I expect photos from your new city" makes a goodbye feel like see-you-later.
