I see, thanks. I suppose in a way that's exactly the opposite of how it is in the Netherlands. Your pension is that which you funded yourself. The AOW (Common Elderdom Law) could be called a state pension (it's not much, ftr), but you probably wouldn't call it a pension because it's the AOW.
(An employer pension sounds like an odd idea.

I hope it works by the employer putting stuff into some "401k" equivalent so it doesn't depend on whether they go bankrupt in the future.)
