Dear [recipient's name]:

As a way to thank employees for dedicated efforts in the past year, we will be distributing year-end bonuses to all employees on December 21. Each employee will receive a separate letter stating the amount of the bonus, which will be included along with the direct deposit for the December 21 paycheck.

If you have questions, please contact Human Resources. We thank you for your hard work this year and look forward to continued success and prosperity as we begin another year together.

Best regards,

[Signature]
