"Where records are maintained, it is recommended that they be kept separately
from the employees basic personnel file or other records available to those
responsible for personnel decisions."
"Any personnel or employment record made or kept by an employer (including but
not necessarily limited to requests for reasonable accommodation, application
forms submitted by applicants and other records having to do with hiring,
promotion, demotion, transfer, lay-off or termination, rates of pay or other
terms of compensation, and selection for training or apprenticeship) shall be
preserved by the employer for a period of one year from the date of the making
of the record or the personnel action involved, whichever occurs later. In the
case of involuntary termination of an employee, the personnel records of the
individual terminated shall be kept for a period of one year from the date of
termination. Where a charge of discrimination has been filed, or an action
brought by the Commission or the Attorney General, against an employer under
Title VII or the ADA, the respondent employer shall preserve all personnel
records relevant to the charge or action until final disposition of the charge
or the action. The term personnel records relevant to the charge, for example,
would include personnel or employment records relating to the aggrieved person
and to all other employees holding positions similar to that held or sought by
the aggrieved person and application forms or test papers completed by an
unsuccessful applicant and by all other candidates for the same position as that
for which the aggrieved person applied and was rejected. The date of final
disposition of the charge or the action means the date of expiration of the
statutory period within which the aggrieved person may bring an action in a U.
S. District Court or, where an action is brought against an employer either by
the aggrieved person, the Commission, or by the Attorney General, the date on
which such litigation is terminated."
