This political perv wants to get paid.

A former de Blasio administration employee and ex-Young Democrat official who pleaded guilty last month to kiddie porn charges is suing the city for back pay.

Jacob Schwartz, 31, faces one to three years behind bars when he’s sentenced next month for downloading more than 3,000 child porn images and 89 videos from the internet, some with victims as young as 6 months old.

Schwartz had worked for the city Department of Design and Construction for two years when he was arrested in May 2017.

He claims he was often paid in “comp time” instead of time and a half when he clocked more than 40 hours a week, and is owed more than $18,000. Schwartz was fired after his arrest.

The Manhattan Federal Court lawsuit was filed by his father, politically connected labor lawyer Arthur Schwartz.

“They owed him money and he tried for two years to get paid,” the elder Schwartz told The Post.

The city will review the complaint, a Law Department spokesman said.
