It's more complicated than that [0]. The fact that you have the right to claim unemployment benefit does not mean that it will be accepted, that it will be accepted quickly or that the benefit will correspond to what you would have had if you had been laid off.

This is true; I can only speak from my experience and that of my peers but the hardest part every time was the "accepted quickly" section of your comment. I am also thinking the process is cryptic and uncertain on purpose to discourage people from even trying. Even though I have not personally seen requests get outright rejected, just drawn out to months.
