Perpetual Guardian, a company is New Zealand that helps people with wills, trusts, and estate plans, employs 240 people and pinned the success of the trial down to employee attitudes. After testing out a four-day work week, the company found that employees reported a 7% stress reduction, a 24% increase in work-life balance, and a 20% increase in team engagement. While staff worked a four day week, they were still paid for five days. They also continued to work eight hour days. Company CEO Andrew Barnes announced the experiment in February, and gave his employees time to improve efficiency across departments – putting it in their hands how a four day week could be done without a loss to productivity.
