Well, it has to be a doomsday prediction, the elite has a very strong interest in keeping the common folks at work. A receding economy is bad, for the people in charge, and the only way to keep it from receding is to increasingly consume, which means increasingly produce.
Companies care about your (mental) health when it's in their direct interest (by paying for mindfulness seminars, ping pong tables, free snacks and other bs), but that's just a way to keep people in check.
You don't have to have a PhD in socio-economics to know that working less directly translates to improved well-being, but well-being isn't going to buy the new porsche and prove the other participants of the global rat race that you're definitely better than them.
"Whereas during the primitive stage of capitalist accumulation “political economy considers the proletarian only as a worker,” who only needs to be allotted the indispensable minimum for maintaining his labor power, and never considers him “in his leisure and humanity,” this ruling- class perspective is revised as soon as commodity abundance reaches a level that requires an additional collaboration from him. Once his workday is over, the worker is suddenly redeemed from the total contempt toward him that is so clearly implied by every aspect of the organization and surveillance of production, and finds himself seemingly treated like a grownup, with a great show of politeness, in his new role as a consumer. At this point the humanism of the commodity takes charge of the worker’s “leisure and humanity” simply because political economy now can and must dominate those spheres as political economy. The “perfected denial of man” has thus taken charge of all human existence." - The society of spectacle
