I was taught in business school (early 2000s) that it was good that GE fired the lowest 10% performing employees b/c the employees were not actually happy or content at GE or they would perform better. Therefore firing them is good b/c they'll find a better career fit elsewhere.

But I actually think it is terrible. It pits co-workers against each other and makes taking credit for an accomplishment more important than doing what's best for the organization.

It's probably good if it's done once every four years. But companies do it every year if not multiple times a year. So at that point, without new blood coming in, you end up cutting into the meat of a high performance org.

IIRC employed during a period where GE was burning the furniture to heat the house. And it was only supposed to be employed temporarily.

That makes sense. I worked there, back when "Neutron Jack" was in charge. I don't remember that, but they probably didn't come out and say it (also, I rated fairly high -they even gave me an award, after I left the company. I still have the plaque, upstairs).
