Paging Randi Weingarten

Shocker! Another school teacher schtupping a teenage boy.

A Queens teacher had sex with her 14-year-old student, hooking up with the boy after school in an empty classroom, then bombarding him with hundreds of cell calls and texts, authorities charged yesterday.

Melissa Weber, 27, of West Babylon, LI, who teaches social studies at MS/IS 8 in Jamaica, had sex with the boy on seven occasions between 3 p.m. and 6 p.m. from April 13 to May 14, authorities said.

And on seven other occasions, she allegedly engaged in inappropriate behavior with the boy.

"Don't tell anyone," Weber, also the boy's homeroom teacher, allegedly told him. "I could get arrested, and I could lose my teaching license."

Sources said the boy's mom grew worried after noticing her son acting oddly and cutting class.

She went to school to investigate on Wednesday, when several people -- including school workers and a student -- hinted at an inappropriate relationship between Weber and her son, the sources said.

The mom found the teacher's phone number, checked her son's cell -- and discovered hundreds of calls and texts between the two, the sources said. One of the last texts allegedly read, "Erase your phone."

Cops arrested Weber yesterday and questioned the boy, who admitted to the affair, the sources said. He had a calendar of the trysts, the sources said.

That's called keeping score.

Knowing those hacks at Randi Weingarten's UFT, they'll probably "suspend" Weber for the summer with pay.
