We have had the opportunity to join the union AFGE (Allied Federal Government Employees) since day one, however, without any real bargaining rights. I haven't joined and may never do so. I feel that I'm compensated appropriately for what I do. I have enough education and experience to earn more if I choose. Currently, I enjoy what I do and the people I work with (including passengers).
I do not KNOW the people that steal. I would hope that it doesn't happen at MSP. I would not look the other way if I saw someone steal. I wouldn't hesitate to turn someone in for anything that resembled misuse of a public trust position.
