The ongoing US government shutdown has intensified concerns over widespread flight delays and unpaid federal workers, as senators failed to reach a resolution on Wednesday. Democrats have repeatedly blocked Republican proposals to reopen government departments, leaving much of the federal workforce either at home or working without pay. Now in its eighth day, the shutdown has led to increased absenteeism among airport security and safety staff, causing growing lines at major hubs across the country. Air traffic controllers, deemed essential, are required to work but are increasingly calling in sick due to financial stress, resulting in staffing shortages. The Federal Aviation Administration (FAA) has reported issues at nearly a dozen airports, including Chicago, Boston, and Houston, with further disruptions anticipated at Newark, a key hub for the New York City area. Transportation Secretary Sean Duffy acknowledged the strain on air traffic controllers, urging them to return to work despite their financial anxieties. He noted that over half of current flight delays are due to staffing shortages, a significant increase from the usual 5 percent. FlightAware reported approximately 10,000 delayed flights on Monday and Tuesday, with the FAA warning of potential worsening conditions. The shutdown shows no signs of ending soon, as Democrats insist on extending health care subsidies for 24 million people in any funding bill. Senate Majority Leader John Thune has repeatedly pushed for a temporary fix, but Democratic opposition remains steadfast. Meanwhile, President Trump has hinted at converting furloughs into permanent layoffs, exacerbating fears among federal workers. A White House memo has further unsettled employees by suggesting they may not receive back pay. The crisis is set to deepen next Wednesday when 1.3 million active-duty service members and thousands of National Guard and Coast Guard personnel miss their first paychecks.
