Some states have laws against employees accessing their personnel files, according to Nolo. Hence, the corporate law varies depending on the state. Personnel files are highly confidential, and some employers allow only legitimate access.
In states where employee access is allowed, the employee can see her personnel file to an extent, according to Nolo. Information pertaining to criminal investigation, references and other such details may not be accessible to the employee. In such a case, the employee should be allowed to see her files only under the supervision of a manager to ensure that no modifications are made to the file, Nolo advises.
