The point of the article isn't to just "work less", but rather that working above and beyond what you're contracted for in a large organization in the long run ultimately won't matter. The takeaway is that your "extra" efforts can be better spent elsewhere: family, personal projects, interviews for next gig, etc.
The article makes it very clear that they're talking about large, 100+ staff companies; when you're just another interchangeable cog in the machine. Today it's seldom that the person doing the layoffs is also part of the day to day operations, hence the you're "just another row in an excel spreadsheet" call out. Anyone who thinks otherwise is deluding themselves by thinking at the boots-on-the-ground level (known individual/quantity, appreciated) instead of the macro COO/CFO costs tracking level (unknown individual/quantity, interchangeable.)
