Airing Saturday, March 29, 9-10 pm on ABC

How do you survive working for a tough boss? What is your favorite office revenge fantasy? What are the hidden career killers? "Work Wars" - how to wage them and how to win them - airs on "20/20 SATURDAY," MARCH 29 (9:00-10:00 p.m., ET) on the ABC Television Network. Anchored by Barbara Walters, reports include:

"I Quit" -- Joey D. Francesco despised his job as a hotel worker, so he decided to quit - not just with the typical two weeks' notice, but in grand fashion. He hired a marching band to come in to his boss' office and blast the news, all captured on video. Francesco is one of a growing number of fed-up workers who videotape their own outrageous quitting. Dan Harris reports.

"Tough Bosses" -- Do you work for an aggressive boss? Learn how to survive from the head shark himself, "Shark Tank's" Kevin O'Leary, the straight-talking "Mr. Wonderful" from the hit ABC show. Elizabeth Vargas reports.

"Black Market Office Supplies" -- Many workers have pilfered the occasional stapler or post-its, but what about $1.5 million worth of toner? Such was the case of Marque Gumbs, who financed a flashy lifestyle of sports cars, Rolex watches, and a ritzy bachelor pad by ordering excess ink as a clerk at Memorial Sloan Kettering, then selling the cartridges for as little as $10. Prosecutors say there is a thriving black market in purloined office supplies. Gio Benitez reports.

"The Bundle" -- Being asked by your boss to do stuff you are not crazy about is a common gripe. But what happens when your boss offers you $10,000 a year for the rest of your life to help dispose of a "bundle" for him. And what if that "bundle" happens to be his dead wife? That happened to one Phoenix man last spring when he was approached by Arizona Shower Door king, Fred Knadler. Knadler was in the middle of a bitter divorce and asked his model employee, Patrick King, to help him out. Jim Avila reports.

"Secret Career Killers" -- Think working hard, making friends in the office and bringing in food for your colleagues is the way to get ahead? Think again. Paula Faris reports.
