This is merely a reiteration of the original point. I have yet to see anything persuasive as to relevance. That is, why is it any different from any other public employment? My understanding is that civil service jobs have specific legal (aka politically-sourced) protections without resorting to techniques from the private sector. ETA: Moreover, politically-motivated firings aren't necessarily arbitrary, though they're obviously not based on merit. The unionized system doesn't appear to be merit-based, either.
