A Brooklyn butcher-shop worker was busted for assaulting a co-worker over the way she was chopping meat, cops said yesterday.

Antonio Pareja, 27, allegedly flew into a rage at Satmar Meats on Myrtle Avenue near Skillman Street in Fort Greene at 9 a.m. on Christmas Eve.

He allegedly screamed at the victim, then started kicking her.

When she tried to flee, he grabbed her by the arm and continued the nasty assault, kicked and punched her, cops said.

Pareja then threatened the woman, saying, “I’m going to have someone hurt your son,” if she reported the attack, according to cops.

The frightened victim reported the incident only after her husband noticed bruises and asked what happened.

Pareja was arrested Monday and charged with assault, menacing and harassment, authorities said.
