Yes. After you have submitted an application for reemployment, your employer can request documentation to establish that:   your application is timely; you have not exceeded the service limitations; and your separation from military service was under honorable conditions.   If you cannot provide satisfactory documentation because it is not readily available or does not exist, the employer still must promptly reemploy you. If after you are reemployed, however, documentation becomes available that shows that you did not meet one or more of the reemployment requirements, the employer may then terminate you. The termination would be effective as of that moment, but would not operate retroactively. If you have been absent for military service for 91 or more days, an employer may delay making retroactive pension contributions until you submit satisfactory documentation. However, contributions will still have to be made for you if you were absent for 90 or fewer days.
