(a) In addition to other records required under the recordkeeping
requirements (part 516 of this chapter), the employer is required to
keep records specific to certification under section 14(a) of the Fair
Labor Standards Act. All workers employed under a subminimum wage
certificate shall be designated as such on the employer's payroll
records. Further recordkeeping requirements are described in each
applicable subpart of this part (see Secs. 520.412 and 520.508 of this
part).
(b) Employers must maintain and preserve all required records for at
least three years from the last date of employment under a subminimum
wage program. The employer's copy of the application and the certificate
shall also be maintained for three years. Such records shall be kept
secure and accessible at the place of employment or where payroll
records are customarily maintained. All records must be available for
inspection and copying by the Administrator.
