This goodbye letter can be sent to coworkers and superiors after resigning from a job.
After {number} years of big dreams, hard work, struggles, mistakes and achievements, it is time for me to announce my resignation. I say goodbye to you all with mixed feelings, but with the unshakeable certainty that this is the correct course of action.
I have enjoyed the opportunity to get to know many of you well. Your dedication, loyalty and focus are sources of inspiration to me. While we may not have a business relationship from here on out, I hope that we can keep in touch, if only through the occasional lunch or a brief email.
I don't yet know what the future holds for me, but I hope you will all wish me luck as I chart my next adventure.
