whistleblower: "One who reveals wrongdoing within an organization to the public or to those in positions of authority."There is a group called Whistleblowers Australia and they produce a monthly newsletter called "The Whistle." (Cleaver, eh?) Click the November 2005 link for a (618kb) .pdf version of the newsletter and look on page 9 for the piece, "Speaking about airports" by John Suter.
Mr. Suter tells a story about his plight as a whistleblower while an employee at Anchorage International Airport that makes you sit up and take notice. Things like unlocked doors that allow people to bypass security, and signs used for target practice with aircraft down range.
For those of you who may not be familiar with American culture, a popular (mostly rural) pastime is shooting guns at roadside traffic signs. Generally, there is no bad effect beyond the defacing of the sign. However, as Mr. Suter recognized, when the sign is along an airport and there are aircraft beyond the sign, you don't really want people shooting guns at the sign. Being labeled a "troublemaker" for pointing this out seems like an example of bad management.
But you can read the article and draw your own conclusions.
