How many FAA employees have been terminated and what positions were affected?

According to recent statements, fewer than 400 FAA employees have been terminated. While the FAA claims that zero air traffic controllers and critical safety personnel were let go, there appears to be disagreement about who qualifies as critical safety personnel. The Guardian reports that those terminated included maintenance mechanics, aeronautical information specialists, environmental protection specialists, aviation safety assistance, and management administration personnel. This has raised concerns about how these terminations might impact the FAA's safety operations and overall efficiency during existing air traffic controller shortages.
