Red-faced court administrators held a statewide conference call with top-level managers on Monday to demand no more unauthorized absences in the wake of a Post exposé about an official who butt-dialed a reporter and inadvertently admitted, “I barely show up to work.”

Chief Administrative Judge Lawrence Marks and Office of Court Administration Executive Director Ronald Younkins laid down the law during the group warning, a spokesman said.

“The message made clear that absolutely no one who works in the state court system is above or exempt from the established policies regarding their time, leave or use of state vehicles,” OCA spokesman Lucian Chalfen said. “The expectation is that they will communicate these sentiments to their staff.”

Chalfen also blasted former communications director David Bookstaver — who was fired from his $166,000-a-year job hours after The Post revealed his accidental confession — for disrespecting Chief Judge Janet DiFiore and her reform efforts, which included speeding up the legal process and beautifying courthouses.

“The actions of one individual in no way reflect the standards, values and goals that the chief judge has championed over the last eighteen months with the Excellence Initiative,” Chalfen said.

Last week, Bookstaver butt-dialed a Post reporter while yukking it up with at least two pals about how “I’m not doing anything” and “I barely show up to work.”
