Great. Another benefit for the salaried over the hourly. I couldn't find a solid answer, but I very much doubt that this pronouncement comes with a 20% raise for everyone paid by the hour.
A 4-day week applicable only to office-working executives and managers is no victory for labor. Imho it is more a failure.
I don't know about Uber, but Amazon has tons of hourly workers - over 750k in fact.
