Among the planned witnesses are a number of bureaucrats who help run the human resources side of government operations, including Deputy Director Office of Personnel Management Christine M. Griffin and Carolyn Taylor, who is the chief human capital officer at the Government Accountability Office.

The hearing comes a little more than a month after President Obama said he believed the economy continued to falter, in part, because there had been layoffs of government employees.

"Our biggest problem when it comes to jobs right now is not in the private sector—we have been creating a lot of private sector jobs,” Obama said. “The reason unemployment is still as high as it is, in part, is because there have been huge layoffs of government workers."

"It frustrates me sometimes when people talk about government jobs as if somehow those are worth less than private sector jobs,” continued Obama. “I think there is nothing more important than working on behalf of the American people."
