The undersigned hereby constitutes and appoints Richard H. Sauer, Juliana

(1) execute for and on behalf of the undersigned, any and all Form ID, or
Form 3, 4 or 5 reports and any amendments thereto required to be filed by
the undersigned, individually or as a trustee, in accordance with Section
16(a) of the Securities Exchange Act of 1934 (the "Exchange Act") and the
rules thereunder with respect to securities of Workday, Inc. ("Workday");
(2) do and perform any and all acts for and on behalf of the undersigned
which may be necessary or desirable to complete and execute any such Form
ID, or Form 3, 4 or 5 report and any amendments thereto and timely file
such report with the United States Securities and Exchange Commission and
any stock exchange or similar authority; and
(3) take any other action of any type whatsoever in connection with the
foregoing which, in the opinion of such attorney-in-fact, may be of
benefit to, in the best interest of, or legally required by, the
undersigned, it being understood that the documents executed by such
attorneyin-fact on behalf of the undersigned, pursuant to this Power of
Attorney, shall be in such form and shall contain such terms and
conditions as such attorney-in-fact may approve in his or her discretion.
The undersigned hereby grants to each such attorney-in-fact full power
and authority to do and perform each and every act and thing whatsoever
requisite, necessary, and proper to be done in the exercise of any of the
rights and powers herein granted, as fully to all intents and purposes as
the undersigned might or could do if personally present, with full power
of substitution or revocation, hereby ratifying and confirming all that
such attorney-in-fact, or his or her substitute or substitutes, shall
lawfully do or cause to be done by virtue of this Power of Attorney and
the rights and powers herein granted.  The undersigned acknowledges that
no such attorneyin-fact, in serving in such capacity at the request of
the undersigned, is hereby assuming, nor is Workday hereby assuming, any
of the undersigned?s responsibilities to comply with Section 16 of the
Exchange Act.
This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Form 3, 4 or 5 reports with
respect to the undersigned?s holdings of and transactions in securities
issued by Workday, unless earlier revoked by the undersigned in a signed
writing delivered to the foregoing attorneys-in-fact. This Power of
Attorney shall terminate, on an individual basis, in the event any of the
granted individuals terminate their employment with Workday, effective as
of their respective termination date with Workday.
IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to
be executed as of this 18th day of June 2024.
