Notes inside farewell cards should be thoughtful and simple. No need to write a dissertation. A few sentences should suffice. Start with a message of congratulations. "Happy Retirement - what a wonderful career!" "Congratulations on the new job. You've earned it!" "I am so excited you will have more time to spend with your family. You won't regret it!" Next, in a few words, describe the impact your colleague had on you and/or the office. "It won't be the same without you. Your positive attitude and friendly smile will be missed." "I've learned a lot from you and I am very grateful our paths crossed." "Thank you for always giving your best and making all of us around you better." "You made the long days around here a lot more bearable. I will miss you tremendously." Finally, end with well wishes for the future. "We will miss you. Please come visit when you're back in town!" "I will be cheering for you from afar!" "All the best to you in this exciting new chapter of your life!" "Enjoy every second of this new adventure. Cheers!"
