most employees say the shortened week has also improved their work-life balance.

This is worded funny, implying there are some who said less hours did not improve work life balance. I can’t really figure that.

FTA:

Most notably, at the one-year mark, 84% of all employees “somewhat” or “strongly” agree that the 32-hour work week has improved their work/life balance.

One reason I can see why someone wouldn’t agree with this statement is because an employee already has a great work/life balance, so while an extra 8 hours (plus commute) of free time is nice, it may not improve their work/life balance.

Also, there are exempt employees who may be negatively impacted by the initiative:

Another concern raised by the report is the fact that exempt employees are having to work more than 32 hours per week. These are salaried employees, not eligible for overtime pay.

…

31% of exempt employees, mostly managers and directors, responded that the initiative has had a negative impact on their workload. Nonetheless, 67% of exempt employee respondents agree that the initiative has improved their work/life balance.
