Respondent Administration for Children's Services' (ACS) determination was supported by substantial evidence ( see CPLR 7803), including several instances of insubordination and disrespect between August and November of 2003. Although petitioner had been an ACS caseworker for nearly seven years, with no prior disciplinary history, the 15-day suspension without pay was not so disproportionate to the offense, in light of all the circumstances, as to be shocking to one's sense of fairness ( Matter of Peters v County of Rensselaer, 28 AD3d 854; see also Matter of Martinez v City of New York, 281 AD2d 187).
