What started as a trial is now a permanent switch.

一開始是實驗，現在轉換成常態性了。

We've seen our happiness go up significantly and we've seen our fatigue come down through the trial so we can prove that our team are happier, less tired and are making more money.

在這個實驗中，我們發現自身的幸福感顯著提高，疲勞感也降低了，因此可以證明我們的團隊更快樂、更少疲勞，並且賺更多錢。

It's pretty cool.

這非常酷。

So how did you do it?

那麼你們是如何做到的呢？

Zero admin, I like to call it.

我喜歡稱它為「零管理」。

We're trying to get rid of as much of the admin as possible that you didn't need to do.

我們正在努力盡可能減少不必要的行政工作。

Our board meetings where it used to be two hours long, they're now half an hour.

我們的董事會會議原本要開兩個小時，現在只需要半個小時。

If you give people this incredible incentive of a whole day of your time a week, they're going to work really hard to become more productive.

如果你給予員工每週一整天的時間作為大大的獎勵，他們會非常努力工作來提高生產力。

Just ask Linda, the office manager.

只要問問辦公室經理 Linda 就知道了。

A day off for me is to get to do the things that I want to do, like this, the litter picking, doing something back for my community near where I live.

對我來說，休息一天就是可以做自己想做的事情，像是清理垃圾，為我所居住的社區做些回饋。

It gives me more time to reflect and be with nature.

這讓我有更多時間反思和與大自然共處。

Are you happier?

你有更快樂嗎？

I am much happier.

我更快樂了。

Healthier?

有更健康嗎？

Healthier. Definitely much healthier, as you can see, it gives us a little bit of exercise as well.

更健康，絕對更健康，正如你所看到的，這也讓我們能稍微運動一下。

Could you ever go back to a five-day week now?

你現在有可能回到每週工作五天嗎？

I wouldn't want to, no. I wouldn't want to, no.

我不希望，一點也不。

It's something that I think more companies should take on.

The results are in for the 61 firms who took part in this six month trial.

39% of employees surveyed said they were less stressed.

There was a 65% reduction in sick days and companies who provided data said revenues stayed broadly the same.

Fewer hours on full pay may not be possible for every employer.

並非每個雇主都能接受工作時間減少但薪水保持不變，

But with many companies finding it hard to attract staff and pay higher wages,

但是由於許多公司發現很難吸引人才並支付較高的薪資，

could this four-day week be a solution and help with the UK's long-running problem of low productivity?

這種每周四天工作制是否可能成為解決方案，並幫助英國長期存在的低生產力問題呢？

I think this trial will be a game changer in terms of momentum in the UK toward a four-day week.

我認為這次實驗將成為英國轉變為實行每周四天工作制的重要契機。

And I'm hopeful that it is going to spur more government interest in this, at all levels of government, and more experimentation and some support for companies who want to go forward

我希望這將激發更多政府對此的關注，無論在各級政府中都如此，並且鼓勵更多的實驗和對希望實行每周四天工作制的企業提供支持及幫助。

How to get the right work-life balance?

如何找到工作與生活之間合適的平衡？

Fewer hours on full pay won't become mainstream any time soon, but this trial suggests there are alternatives to the traditional five-day week.

較少的工作時間但領全薪在短時間內不太可能成為主流，但這個實驗顯示了傳統的五天工作制的替代方案。
