Nope, because productivity is output divided by hours worked, so working longer can decrease productivity.

I think youre just using a different definition of productivity. Hourly is valid, but yearly is too.

https://en.wikipedia.org/wiki/Total_factor_productivity is my definition, as it's the one that actually gets talked about in the press (as opposed to the nebulous "productivity" beloved of tech people (including me)).
