15 biggest job losers

Even as the Fortune 500 racked up astounding profit growth of 335% last year, a whopping 761,422 Fortune 500 jobs were lost to layoffs, spinoffs, and attrition. These 15 companies saw the worst cutbacks.

In the midst of the credit crunch, the bank holding company laid off more than 55,000 employees in 2008. Then last year, as it struggled to regain profitability and pay back a $25 billion government bailout loan, Citi cut its staff again by another 57,700 workers. Despite the cutbacks, the company still posted a loss of $1.6 billion in 2009.
