WASHINGTON, Oct 8 (Reuters) - U.S. Transportation

Secretary Sean Duffy said on Wednesday that flight delays tied

to air traffic staffing issues have jumped dramatically in

recent days as a government shutdown enters its eighth day.

"Historically, there's about a 5% of delays that is

attributed to staffing issues in our towers. Last couple days it

has been 53%," Duffy said on Fox News.

"My message to the air traffic controllers who work for DOT

is show up for work -- you have a job to do." He added "the

bottom line is these controllers are stressed out, and they're

rebelling on this shutdown because they may not get paid."
