It could be because I am changing my business. Let's say I am a Big Tech Company. I make Gadgets and Widgets. If I decide I don't want to make Gadgets any more and make only Widgets, then I don't need the people who make Gadgets. SOME of the people who made Gadgets could be retrained/repurposed to make Widgets, but some can't (or don't want to). Those are the people whose jobs I will cut. And of course, I will use some of my "tons of cash in the bank" to give them severance packages to compensate while they search for jobs in other companies who make Gadgets.
