The undersigned hereby constitutes and appoints Richard H. Sauer, Juliana Capata, Benjamin Uy, and Angela Barber, and each of them individually, as his or her true and lawful attorney in fact to:

          (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 attorney in 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 attorney in 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 25th day of February 2020.
