Maybe you spent every morning cursing yet another commute to a job you hate; but, hopefully, you loved your job, and the time to enter the golden age of retirement has simply come.

A farewell letter is perhaps your final opportunity to top off your legacy with the company and to thank all of the people who have helped you throughout the years. This is not an email that you can dash off in ten minutes. Spend time reviewing the tools at this TabStart page to make sure that your farewell is one that colleagues will save in their in inboxes for years to come.
