Aviation officers represented by SEIU Local 73 upped their criticism of Chicago Department of Aviation Commissioner Ginger Evans last week, sending her a letter of no confidence that said she’s made “repeated attempts to downgrade their ability to protect public safety.” Evans’ office announced it would institute new measures meant to enforce that Aviation Security Officers (ASOs) “perform security functions, not policing functions” at the city’s airports, and repeating a January mandate that the word “police” be removed from uniforms and ASO vehicles.
