A significant factor for the making the list this year is being able to create jobs. The 100 companies on the 2008 list added 67,000 employees to their payrolls in the past year and employ a total of nearly 1.6 million employees, up 16% from the number employed by companies comprising last year's list. Chesapeake alone added approximately 1300 new employees in 2007.

To pick the "100 Best Companies to Work For," FORTUNE worked with Robert Levering and Milton Moskowitz of the Great Place to Work Institute to conduct the most extensive employee survey in corporate America. Of some 1,500 firms that were contacted, 406 companies participated in this year's survey. Nearly 100,000 employees at those companies responded to a 57-question survey created by the Great Place to Work Institute, a global research and consulting firm with offices in 30 countries.

Two-thirds of a company's score was based on the results of the survey that was sent to a minimum of 400 randomly selected employees from each company. The survey asks questions related to their attitudes about the management's credibility, job satisfaction and camaraderie. The other third of the scoring is based on the company's responses to the Institute's Culture Audit, which includes detailed questions about pay and benefit programs and a series of open-ended questions about hiring practices, methods of internal communications, training, recognition programs and diversity efforts.

Any company that is at least seven years old with more the 1,000 U.S. employees is eligible. The deadline for applying for next year's list is March 31, 2008. For an online nomination form, go to
