I've worked for a number of tech companies in the US and many of them could easily move to a 4 day workweek. Reason I say that is at every place, there was a culture of slacking off on a Friday. Not in an overt way but you could tell, meetings wouldn't be scheduled after 10AM on Friday, any meeting would be short and sweet. Any longer meetings would be pushed off to Monday. Slack is usually pretty quiet, and the green dots turn grey starting around 1PM. The bosses could do something about it, but they don't because they also don't want meetings and are just looking forward to the weekend themselves. The only time you would even hear from bosses is a reminder to submit your timesheet before leaving for the weekend.
