Privatizations and Pensions

[Guest Southern FA]

I am looking for an extensive list of issues when a public sector utility, airport authority, or insurance authority goes private. For example, as private sector employees, what happens with those who are vested in their public sector pension system, but are not yet retired? I am guessing that even if there was a single employer pension system, it can't/won't transform into a private sector system, but a new private sector system might be created.
