MTA Inspector General Carolyn Pokorny caught Andrea Abaquin breaking the rules on three different fronts — and Abaquin is a compliance and ethics manager. Why wasn’t she fired?

These weren’t trivial offenses: She lied about her hours, claiming she left work after an eight-hour day to pick up her daughter from school, when a MetroCard records review showed she often left early — sometimes after as little as three hours of work.

She also used her work-only MetroCard for personal trips and didn’t disclose that her spouse worked for an agency contractor.

And, the inspector general reports, Abaquin denied any wrongdoing until investigators confronted her with the evidence. No wonder the MTA can’t rein in overtime abuses by workers: Its managers are cheating, too.

And getting away with it: Abaquin earned only a two-week suspension without pay plus a “fine” of $1,848 to compensate for her abuse of her agency transit pass. With that, she was back to enforcing ethics rules.

Nor was she the only errant employee to get soft treatment.

Last year, the IG found that a MTA computer specialist busted in 2013 for a dual-employment violation was back to operating his personal business during work hours and using MTA resources.

And even after getting caught a second time, he merely got hit with a a 30-day suspension plus a “final warning.” For his admitted violation of the Public Officers Law, the state Joint Commission on Public Ethics recommended against added financial penalties because he’d lost $6,500 in pay during his suspension.

Pokorny’s annual report highlights over a dozen investigations involving similar outrages. The number of complaints her office received more than doubled, from 683 in 2018 to 1,375 last year. In 2019, that led to 232 investigations and inquiries, 108 closed investigations, with 173 probes still open.

But all the IG’s work won’t mean much unless MTA leaders start imposing serious penalties for such flagrant abuses.
