back to article Results are in for biggest 4-day work week trial ever: 92% sticking with it

The massive British trial of a shortened four-day work week is over – and it's food for thought for companies battling to attract and keep high value employees as one of the side effects was a large drop in staff attrition. Most of the companies involved said they would continue offering a shorter week. Of the 61 companies …

    What day wouldn't you work?

    I do a 4 day week with Wednesday off and think it is great.

      If it's regular I would also go for Wednesdays, though ideally would be flexible enough to take the occasional Friday instead to make use of long weekends eg on Bank Holidays

      1. Disgusted Of Tunbridge Wells Silver badge

        I wonder if it would be more productive to have an uninterrupted four day week or whether keeping the "what was I working on on Friday?" effect at bay by having a two day weekend plus Wednesday.

        I assume the study covered this.

        1. Binraider Silver badge

          Un-interrupted would definitely be better. A 3-day weekend is also a whole lot more useful than a random day midweek.

    2. Snake Silver badge

      I've been working 4-day work weeks for almost 14 years now and would never go back to 5 day. Just not interested, no matter how much more lucre it may theoretically bring me. As the rest of the world considers the 4-day week, I've only been left to think "What has taken you so long??".

      I do 4 days with Monday off, so I get 3-day weekends. I'd rather be on my motorcycle than just about anyplace else on planet Earth, so it's great.

      1. Michael Wojcik Silver badge

        I'm definitely in favor of this for those who want it, but since I spend my weekends working on the houses and grounds anyway, or engaged in other productive pursuits, I'm personally not interested.

        I generally end up doing some employer-related work most days, weekends included, because I enjoy it and it's nice to take a hour or so break from more physically-demanding labor. If I'm not doing one of those, I'm probably reading, but unlike in my earlier years I find I can't sit and read for more than a couple of hours at a time. And most days I get out for a bit of a walk or bike ride, but again that's only an hour or so (generally; once in a while I'll do a day hike).

        But that's my preference, and for most folks it seems a 4-day work week would be more efficient and give people more personal time without hurting productivity.

      My four day work week is Tuesday until Friday. Since I live in the future waiting for the rest of the world to catch up, er I mean Eastern Australia, during my Monday it's still the weekend somewhere in the world.

      This is my form of semi-retirement. If four days catches on in the rest of the world, I'll have to reduce my work week to three days. Tuesday to Thursday sounds good.

      Also, this being the land of the long weekend, most holidays are moved to the nearest Monday or Friday. If they are on Monday I take Tuesday off.

      Wednesday feels like the ideal day as it breaks the week up enough to make being sent away on business travel a lot less practical. Taking time out for travel you'd not get long enough at the other end to make the trip worth the cost or effort.

      After a long period of proving we could run this business via remote meetings, I'm finding it incredibly frustrating that manglement are falling back to the old ways of expecting business travel to be the norm...putting a big Wednesday-sized obstacle in the way would be a useful way of showing that remote meetings should still be a used in preference to travel.

      1. Michael Wojcik Silver badge

        Interesting. I used to do a fair bit of business travel, but years ago my employer started cutting back, and I'm not seeing any signs of it resuming for me, at least.

        I actually wouldn't mind a trip to HQ every couple of years or so. Going out there for a week was a bit of a lark, seeing folks in person again, wandering around a foreign area, and whatnot.

      I work a 4 day week but still do 36+ hours a week. I find it nice. I have a Tuesday off usually but can work round other commitments.

      It is nice as can get things sorted at home in normal working hours - getting appointments for things is so much easier than in an evening/weekend.

      I found the article strange to say 4 days and no hours change, I'm sure everyone would be pleased if they are paid for a 37.5 hour work week (5 days) but only did 30 hours (4 days) of actual work. Seems a good deal.

        "I found the article strange to say 4 days and no hours change, I'm sure everyone would be pleased if they are paid for a 37.5 hour work week (5 days) but only did 30 hours (4 days) of actual work. Seems a good deal."

        From the article "The crucial point of the pilot, in which 3,000 UK-based employees participated, was that no one's salaries changed, nor were they required to work extended hours, the so-called "4×10 schedule" (four 10-hour shifts) tested by Atlassian and others."

        I think there may be different trials being referred to here or different companies trialled different ways of achieving a 4 day week.

        Back in the day, when I was late teens and working at the local swimming pool, we switched to a 4 day week with 2x10 + 2x9.5 (39 hour week was standard then). It was great. Closed on Sundays and about about every 6 weeks, the shift pattern meant days off were Fri, Sat & Sun followed the next weeks pattern of Mon, Tues, Sun so almost a week off every 6 weeks :-)

    7. M.V. Lipvig Silver badge

      I've been on 4x10, working Thursday through Sunday, for more than 10 years now. 10 hours vs 8 hours is barely noticeable, but 3 days off is wonderful. It helps that I work in a 24x7 shop full of people mentally locked into wanting the weekends off on their 5 day workweeks. My being willing to work both weekend days takes pressure off The Boss where coverage is concerned.

      For me, having 3 weekdays off per week lets me take care of business when business is open. Shopping is easier as well, as instead of being in the shops on the weekend with thousands of others it's just me and a small bunch of pensioners. It's rare when I have to wait in line to check out.

      If they did switch to 4x8s, I'd see of they would let me do 3x11s. I wouldn't notice the extra hour (I already actually work 11 for a bit of overtime) so again, no difference to me on the workday but the extra day off would be stellar - and I'd Thursdays off.

    Short-term observations

    Although the outcome of this study is hardly surprising, one has to wonder how long it will take workers to reestablish their baseline level of discontent to the 4-day work week, resulting in a concomitant drop in productivity. It seems like you'd really need to track output over the course of several years in order to gather reasonably conclusive data. It also seems like there are so many variables in play that conclusively establishing what happens to employee output over time will be quite challenging.

    Not to say that I oppose the idea, mind you . . . if my old job in IT Operations had been only four days (plus being on-call 24/7, of course), perhaps I wouldn't have burnt out.

    1. doublelayer Silver badge

      Re: Short-term observations

      I agree, unfortunately. I'd really like a four-day week, and if my employer did this maybe we'd try cutting back on the pointless meetings and make processes more efficient. However, there's a reason it got this inefficient in the first place, so if we were permanently on a four-day week, they'd start reintroducing the sources of the problems and productivity would fall again. Companies have many incentives to cut inefficient processes like too many meetings, but so few of them do it. I don't think shrinking the work week will make them do it.

        When I was an undergraduate, I was living north of Boston, going to school in Boston, working one job just outside Boston, and working another to the west of Boston.

        My total commute time was ... well, it was long, though the exact time varied depending on how many of those places I went to on a given day, and what transport modes I used. But often I took the train or a bus + train combination, with a car ride back home in the evening with one of my co-workers. On public transport I could read for work, school, or pleasure, so I didn't feel that was wasted time.

        On days when I got out of the house too late to catch my bus or train and had to drive, it was a different story. I could easily end up losing close to four hours on such days. That was a ridiculous waste of my time, but I really had no one to blame but myself.

    I may have missed it but does anyone have a link to the study. I've seen some reporting on it but have a few questions I'd like answering:

    1. What was the mix public:private

    2. What was the mix service:manufacturing

    One of the companies mentioned in the beebs coverage was an "environmental consultancy". Consultancies will either charge on an hours booked (note I do not say worked) or a per project basis. If charges are on an hours booked basis how can this not result in lower billings? If on a project basis I can see that wasting less time in meetings would keep revenues up but if management have allowed this time wasting already it will creep back.

    In the beeb reporting there was also mention of a fish & chip shop. Unless they reduce opening hours then surely this simply means more staff since I'm not sure how you'd get productivity improvements - rush the customers perhaps?

    Cost of Offices

    Is this now also influenced by the cost of the work space?

    If everyone has the same day off then the company saves 1/5th on the heating and electricity in the office space for the day

      Re: Cost of Offices

      OTH, if 20% or the workforce takes different days off, the company can reduce their office space by 20%. Probably a lot more savings than the heating and electricity reduction of a one day per week office closing.

        Re: Cost of Offices

        I suspect that would be more likely since otherwise you'd have some companies operating, eg Mon-Thurs, some operating Tues-Fri and other Mon-Fri. Companies need to interact with other companies so without a national decision for everyone to go Mon-Thurs confusion will likely abound. Likewise, with this international interconnected world, there would still be problems dealing with the rest of the world. Time zones already cause enough confusion without wondering whether a particular company will be operating on a particular day.

    A levels...

    Back when I did A level business studies, one of the topics discussed as about improving workplace efficiency. It being quite some time ago now, I have no idea what the references are for it, but there were studies that showed that productivity will improve when you introduce new schemes and incentives. Eg. people feel more valued when they get better lighting and chairs, so they work more effectively.

    However, the same studies showed that taking those things away again didn't reduce productivity by anywhere as much as it increased.

    I suspect with this scheme, we're seeing similar. If the businesses went back to 5 day weeks, but kept the other small changes - reduced meetings etc, then I'd guess they would see an increase in productivity close to an extra day's work.

    Just don't let the managers catch on.

      Maybe never if it becomes standard. Few people work a 6 day week[*] these days since that new fangled idea of only working 5 days caught on :-)

      * some of the people posting above excepted of course. Although anyone working 50-60 or more hours per week, especially where it's expected, standard and in some cases even unpaid, well, you're in the wrong job. Ok maybe for a short period, or to gain experience but anyone on a fixed salary should only be doing extra hours when it's needed, ie exceptions, not standard practice and should be a decent enough salary to account for those hours. Voluntarily working more hours for more pay because you need or want the extra cash is a different thing.

    Looking through the majority of companies, there really are not many surprises among the type of companies involved.

    Indeed, it is a 'not for profit' group that is largely checking whether other charity/public sector/linked businesses enjoyed working 4 day weeks.

    In exchange for reducing their work days by 52 days per year, they did not a typical reduction of 2 days per year sick leave.

    So yes, as expected, those funded by charitable means and via council/government cash, found that their employees liked working 4 days a week for the same money.

    Notably, no plumbers or manufacturing firms chose to join the study, although I will admit the curiousity that 'Atom Bank' did actually take part.

    I don't think this will gain any traction in the so-called 'dirty trades' where pay is based on actual work output.

      I've not seen it debunked. All I've seen is a lot of people, usually ones who like WFH, saying it isn't true. I can't call something disproved on the basis of "a lot of people don't think it is true". Neither does that prove that it is true after all. I've seen no useful data to making a factual statement about it, and given that it would require some objective judgement on how creative an idea was and how the idea came to exist in someone's head, it might not be possible to prove it either way definitively.

Often not related to my specific bit of the project, but useful to know more about other areas and how the product is used - makes it more meaningful knowing how my bit fits in with the rest of the project, and how the customer gets to abuse it.

    What a surprise. Not.

    Campaign groups do a study. Study says that the campaign groups are right.

    Mind you, I'd like to believe the study's results, but wishing it so doesn't make it so. Wake me up when an independent study appears.
