On 1/23/19, National Air Traffic Controllers Association (NATCA), Air Line Pilots Association (ALPA), and Association of Flight Attendants-CWA (AFA) released a joint statement, which includes this shocker (highlighting mine):
Due to the shutdown, air traffic controllers… and many other critical workers have been working without pay for over a month. Staffing in our air traffic control facilities is already at a 30-year low and controllers are only able to maintain the system’s efficiency and capacity by working overtime, including 10-hour days and 6-day workweeks at many of our nation’s busiest facilities. Due to the shutdown, the FAA has frozen hiring and shuttered its training academy, so there is no plan in effect to fill the FAA’s critical staffing need. Even if the FAA were hiring, it takes two to four years to become fully facility certified and achieve Certified Professional Controller (CPC) status. Almost 20% of CPCs are eligible to retire today. There are no options to keep these professionals at work without a paycheck when they can no longer afford to support their families. When they elect to retire, the National Airspace System (NAS) will be crippled.
