For everyone on salary, just say: "our new office culture is a 2.5 day week."
For everyone on hourly wages, just double their wages and they'll adjust their own schedules.
The trick is to do so simultaneously across the world to discourage scabs.
That'd work for many, but many others would seek another job the same.

That definitely doesn't work. Where has introducing or raising minimum wage caused workers to seek fewer hours, for real but less extreme example?
I guess we haven't yet saturated the demand for wages.
