A CUNY administrator who gets paid $106,700 a year in taxpayer funds is now suing for $8 million because he has “nothing to do.”

Harendra “Harold” Sirisena, once the bursar at New York City College of Technology, has had his duties gradually slashed over the past 14 years for no reason, he claims in a federal discrimination lawsuit.

Yet he continues to collect a fat paycheck — and even gets contractual raises. Since last fiscal year, his salary has jumped by nearly $10,000.

Sirisena, 72, told the Post he sits idly in a tiny cubicle from 7am to 3 pm, listening to music, watching cricket or rugby games online, and sometimes dozing off.

“I am just there. There is no work for me,” he said. “Sometimes I fall asleep at the desk.”

When Sirisena spoke to The Post last year, he said his sole assigned task — plugging names onto form letters — took up an average 30 days a year. That left 171 days, or 86 percent of his time.

But after the embarrassing publicity, he said, he’s getting paid more to do even less.

“He’s now at the point where he has nothing to do,” said his lawyer, Oliver Koppell, a former New York attorney general. “It’s an outrage– and weird.”

The demotions and “employment gap” have left Sirisena stuck in his dead-end position — unable to transfer within the CUNY system or find a job elsewhere, he complains in his Brooklyn federal court suit.

“The banishment and deprivation of work extracted a substantial psychological and emotional toll” on Sirisena, the suit charges. It demands that CUNY restore him to useful work.

“Who can spend 14 years in a little cubicle, doing nothing?” he asked “The insult, the humiliation — what did I do?”

The suit charges age and race discrimination. Sirisena is a native of Sri Lanka.

For eight years, starting in 1995, Sirisena was director of the bursar’s office — responsible for tuition collection, payroll and bank deposits.

His work was praised for “innovation, productivity and efficiency,” the suit says. He also helped students with financial aid: “They all loved me,” he said.

In 1998, he applied to become a Higher Education Officer — up the management ladder — but was repeatedly rejected, the suit says.

In 2003 he was banished to a “rubber room,” and languished there for two years with no assigned work.

He was replaced as bursar by a young, unqualified office assistant, the suit says. After that bursar died in October, a woman with little experience took over, Sirisena said.

During his years of minimal duties, Sirisena has collected more than $1 million in paychecks.

He has begged his bosses, in vain, for an explanation, he says.

CUNY has claimed Sirisena “lacked the necessary computer skills for his position,” though he holds a certificate in computer programming from NYU, as well as a master’s degree in international affairs and socioeconomic development from Columbia University.

He worked four years in the bursar’s office at The New School before joining CUNY because he wanted to serve low-income students.
