UPS wants to deliver this message to one of its ex-employees: You’re fired, now beat it!

The shipping giant claimed in a lawsuit filed Tuesday that a New York man -- booted by the company for workplace violence in 2008 -- has been showing up at the office, insisting he’s still employed.

Wesley Anderson, 28, of Brooklyn, popped up at least five times this past year -- from July to October -- at the facility at 643 W. 43rd St. in Manhattan, according to the suit in Manhattan Supreme Court, the New York Post reported.

The suit wants Anderson permanently barred from the site -- and it is seeking damages for the Big Brown Machine, because of the problems he has allegedly caused.

UPS claims Anderson could go postal if he’s not kept away.

"As a former employee, defendant Anderson has unique knowledge of the 43rd Street facility's various entrances and security procedures," UPS said in its lawsuit.

Anderson was hired August 22, 2000, as a part-time preloader before he was first dumped in 2008 for alleged workplace rage, the complaint said.

A union grievance and promises to seek anger management won Anderson his job back temporarily. But he then got permanently canned on September 5, 2008, after Anderson got into a package-hurling fight with another employee, UPS claims.

Anderson was arrested after one of his efforts to get back into his former workplace in October, prosecutors said. He has a pending case, charged with misdemeanor trespassing.

The ex-worker was unable to be reached for comment.
