IN RE: Kenneth JOHNSON (2006)

In a proceeding pursuant to CPLR article 78 to review a determination terminating the petitioner's probationary employment with the Department of Design and Construction of the City of New York, the appeal, as limited by the appellants' brief, is from so much of an order and judgment (one paper) of the Supreme Court, Queens County (O'Donoghue, J.), dated February 25, 2005, as annulled the determination, reinstated the petitioner to the position of Mechanical Engineer, Level I, retroactive to the last date of his employment, with full back pay and all accrued emoluments of employment, and directed that the petitioner be assigned work commensurate with his civil service title.

ORDERED that the order and judgment is affirmed insofar as appealed from, with costs.

 The petitioner was a probationary employee with the Department of Design and Construction of the City of New York (hereinafter the DDC) and, as such, his employment could be terminated for any reason, so long as the termination was not in bad faith, for a constitutionally impermissible reason, or in violation of statutory or decisional law (see Matter of Swinton v. Safir, 93 N.Y.2d 758, 763, 697 N.Y.S.2d 869, 720 N.E.2d 89;  Matter of York v. McGuire, 63 N.Y.2d 760, 480 N.Y.S.2d 320, 469 N.E.2d 838;  Matter of Robinson v. Health and Hosps. Corp., 29 A.D.3d 807, 815 N.Y.S.2d 222;  Walsh v. New York State Thruway Auth., 24 A.D.3d 755, 757, 808 N.Y.S.2d 710;  Matter of Hernandez v. City of White Plains, 301 A.D.2d 523, 524, 753 N.Y.S.2d 731).   The petitioner claims that his employment was terminated in retaliation for his filing of a union grievance.   Thus, the petitioner had the burden of proving (a) that he was engaged in protected union activity, (b) that the DDC had knowledge of the activity, and (c) that he would not have been discharged from employment but for the activity (see Matter of Rockville Ctr. Teachers Assn., NYSUT, AFT, AFL-CIO v. New York State Pub. Empl. Relations Bd., 281 A.D.2d 425, 425-426, 721 N.Y.S.2d 112).

 The Supreme Court properly determined that the petitioner established a prima facie case of improper motivation.   The burden of persuasion, therefore, shifted to the DDC to establish that its actions were motivated by a legitimate business reason (see Matter of Board of Educ. of Deer Park Union Free School Dist. v. New York State Pub. Empl. Relations Bd., 167 A.D.2d 398, 399, 561 N.Y.S.2d 810).   The DDC failed to meet this burden, and the Supreme Court properly, inter alia, annulled the DDC's determination and reinstated the petitioner to the position of Mechanical Engineer, Level I, with full back pay.
