International media mogul Rupert Murdoch's house of cards is about to crumble. Here's why: his employees hate him.

For those of us in the news industry, like myself, Murdoch's reputation for ruthlessness among his middle executives is notorious. His shoddy treatment among literally thousands of News Corp. workers across the U.S. in the early days of his rise to power knew no bounds. When you build up years of personal enemies, given the chance to sing, they'll all become birds when they get the chance to spill the beans on the guy. 

Money is money. Power is power. They come and go. But nastiness stays around for life. Ex-employees who feel they were mistreated -- they never go away. And they'll soon have their day in the U.S. media, just like they are having now in the U.K. 

After his testimony in Parliament last week was challenged by two former senior employees and referred by a lawmaker to Scotland Yard for investigation, Murdoch has come under rising pressure in Britain's phone hacking scandal that is likely to intensify this week, as he confronts a series of behind-the-scenes battles as he seeks to stabilize his status at the media giant.

The master of the "spin" is about to implode. 

Parliament's remarkable three-hour hearing July 19, focusing on the role of Rupert Murdoch and top News International executives in the immense phone-hacking scandal, proved an epic "Westminster moment." 

The world will soon catch a glimpse of how Murdoch and his band of unscrupulous henchmen -- masquerading as "journalists" -- gained control of the Brit's political elite, the media and the cops. Control the politicians and you have power. Control the media and you keep your power through fear. Control the cops and keep your fear intact, unchecked. It's a simple mathematical equation. Hitler used it very adroitly in pre-war Germany. 

There is an Australian story about the young Rupert Murdoch, who inherited his first newspaper from his late father in Sydney in 1955 When confronted by a local politician who was displeased with his paper's coverage, Murdoch reportedly answered: "What do you want? A bouquet of roses every day, or a bucket of shit every day?"

Murdoch, has a history of living by its own rules and operating beyond consequence. That ended last week.
