§ 1002.122 Is the employer required to reemploy the employee if documentation establishing the employee's eligibility does not exist or is not readily available?

Yes. The employer is not permitted to delay or deny reemployment by demanding documentation that does not exist or is not readily available. The employee is not liable for administrative delays in the issuance of military documentation. If the employee is reemployed after an absence from employment for more than 90 days, the employer may require that he or she submit the documentation establishing entitlement to reemployment before treating the employee as not having had a break in service for pension purposes. If the documentation is received after reemployment and it shows that the employee is not entitled to reemployment, the employer may terminate employment and any rights or benefits that the employee may have been granted.
