As someone replied to your other comment with, this is not correct. Firing does indeed refer to termination, which is different from redundancy. It's a colloquial term rather than a legal one, but firing is to termination as laying off is to redundancy.

These distinctions may mean less in countries without robust worker protections where the lines between the two might be blurred, but in a lot of the world these are quite distinct concepts.
