Put yourself in the position of someone at Eskom that's been there a good few years and has some valuable experience and knowledge.
You probably spend your days too shi*t-scared to admit where you work and when you finally do its met with some sort of apology for being part of the big-bad.
Now listen to the general public moan and gripe and swear blind that every person at Eskom is corrupt/lazy/incompetent (or all 3).
Now add to that the media's relentless pursuit of an Eskom story, some of which you know to be true and the other patent BS.
Why would you stay? Why would you not move on? Why would you not take advantage of the countless opportunities overseas where your skillset is in short supply?
