Reservist Pay Security Act of 2001 - Entitles a person who is absent from his or her position of Federal employment to perform service in the uniformed services or the National Guard to receive from his or her agency an amount that, when added to the pay and allowances for such service, equals the basic pay which would have been payable to such employee for such period of service for which such employee is not otherwise compensated.
To ensure that a Federal employee who takes leave without pay in order to perform service as a member of the uniformed services or member of the National Guard shall continue to receive pay in an amount which, when taken together with the pay and allowances such individual is receiving for such service, will be no less than the basic pay such individual would then be receiving if no interruption in employment had occurred.
