Pension-system head leaving amid probe into her hiring ex

The head of the city’s largest pension system is leaving her $219,771-a-year job amid an investigation into the hiring of her former live-in girlfriend.

Diane D’Alessandro, executive director of the New York City Employees’ Retirement System, said she’ll retire effective Dec. 31 from the agency that manages pension benefits for some 300,000 workers and retirees.

“The time is right for me to pursue something new,” D’Alessandro said in a memo thanking staff.

She’s quitting nine months after hiring her ex-domestic partner, Ellen Carton, as deputy director of human resources with a $127,000 salary. D’Alessandro had previously awarded two consulting contracts to a two-person Arizona firm joined by Carton, The Post found.

After the Post report, the city Department of Investigation launched an ongoing probe.
