While I have my reservations about a permanent 4-day workweek, it's not clear to me that's the defining characteristic of Bolt that caused it to lay off 1/3 of employees. It could as easily be described as "Bolt, the SF payment services startup, lays off 1/3 of employees", and that would suggest something very different about the cause.<p>Now I suppose it could be that a 5th workday per week would have changed this outcome, but it could equally be that a payment services startup in an economy headed into recession, is not well positioned to grow as much as it thought when it hired the last few hundred people, thus it needed to shrink.<p>Again, I'm not saying a 4-day workweek is necessarily going to work out for most companies, but it seems like the business a company is in, is a more likely factor leading to layoffs.
