If you would like to appreciate someone for their good work or a job well done, here is a simple template you can use to write an appreciation letter for good work.
Words can’t express how great of a job you’ve done since you’ve worked for us. I can see the hard work and dedication you’ve put in every time you come to work. We want to let you know that all your hard work didn’t get unnoticed. We’re more than happy to let you know that we decided to give you a little bonus as appreciation for everything you’ve done for us.
If you want to continue working for us, you are more than welcome to do so. We would be more than happy to have someone like you work for us in the coming years. You can even serve as a role model to other employees.
