Samples of employee complaint letters can be found online through websites such as letters.org and writeexpress.com. Samples may also be available from the websites of law firms such as rocketlawyer.com or from a local lawyer or from a human relations representative.
When writing a letter of complaint, it is important to clearly state the concern without using inflammatory or abusive language. The letter should remain as specific as possible while sticking to the point. An employee complaint can be addressed to a direct supervisor or to a human resources representative. It is important to save a copy of the letter, either on a computer or by keeping a hard copy.
