Missouri: Employee Personnel File Access Requirements
The short answer
Missouri has no general law requiring a private employer to open or copy the full personnel file. It instead has narrow letter rights: a qualifying former employee of a corporation with at least seven employees may demand a service letter within 45 days, and a current or former employee receives or may request a copy of certain reference letters sent to a prospective employer. Those laws do not create access to evaluations, discipline, applications, training, or the rest of the HR file.

| Records covered | No inspectable file; narrow letters cover service nature/character, duration, and reason for discharge or quit (§§ 290.140, .152) |
| Excluded or redacted records | Evaluations, applications, discipline, grievances, training, and other personnel-file material remain outside the narrow letter statutes |

What an employee can request without full-file access
Missouri does not require a private employer to open the full personnel file. Its narrow letter statutes instead address separation and employment references.
A former employee may demand a service letter only after at least 90 days with a corporation that employs seven or more people. The employee must send a written certified-mail request within one year after leaving, direct it to the superintendent, manager, or registered agent, and specifically reference § 290.140. The corporation then has 45 days to state the nature, character, and duration of service and truthfully give any reason for discharge or voluntary departure.
Separately, when an employer sends a written response about a current or former employee to a prospective employer, § 290.152 requires a copy to be sent to the employee's last known address. The employee may also request that letter for up to one year after its date.
What trips people up
The service-letter law is not an inspection right. It produces one signed summary letter, not applications, evaluations, disciplinary records, investigation material, training records, or the employer's underlying file.
Eligibility is unusually specific. The employer must be a corporation with at least seven employees, service must have lasted at least 90 days, and the certified-mail request must cite the statute. A request that misses those statutory conditions is not the demand described by § 290.140.
Common questions
Can I request my entire file?
Missouri has no general statute requiring an ordinary private employer to provide it. Employer policy or an agreement may offer broader voluntary access.
How long does the corporation have for a service letter?
Forty-five days after receiving a qualifying request.
Can I see what my employer told a prospective employer?
Yes, when the communication is the written response governed by § 290.152. The employer must send a copy, and the employee may request it for up to one year after the letter.
