Washington (CNN) White House economic adviser Kevin Hassett said furloughed federal workers who are not getting paid during the partial government shutdown are "better off" because they didn't have to use vacation days.

"Huge share of government workers were going to take vacation days, say between Christmas and New Year's. And then we have a shutdown and so they can't go to work, and so then they have the vacation but they don't have to use their vacation days," Hassett told PBS during an appearance on "NewsHour."

On Saturday, the ongoing partial government shutdown broke the record to become the longest government shutdown in US history -- with no end in sight. The shutdown has impacted roughly a quarter of the federal government and hundreds of thousands of federal workers. An estimated 800,000 federal workers have been affected by the lapse in funding -- either by having to work without pay while it lasts or by being furloughed.

"And then they come back and then they get their back pay, then they're, in some sense they're better off," Hassett said.

Last week, Congress passed legislation sponsored by Democratic Sen. Ben Cardin of Maryland to guarantee back pay for federal workers who have been furloughed during the government shutdown. But federal employees -- those on furlough and those who have remained on the job -- still won't be paid until the shutdown ends.
