What is never found in an employee's personnel file?

The I-9 form is a critical document required by federal law for verifying employees' eligibility to work in the United States. However, it is not typically retained in an employee's personnel file. Instead, employers are required to keep I-9 forms in a separate file to ensure compliance with federal regulations regarding employee verification. This separation helps protect sensitive information related to an employee's immigration status from being included in their general personnel file, where information might be more accessible to individuals who do not need to see it.

In contrast, the other documents, such as the W-2 form, training certifications, and job descriptions, are essential components of an employee's employment record and are usually maintained within the personnel file for reference regarding compensation, qualifications, and job responsibilities.
