The Rise of the 9 p.m. Work Hour (theatlantic.com) 84

An anonymous reader shares a report: Last week, Microsoft published a study that offers an eerie reflection of my working life. Traditionally, the researchers said, white-collar workers -- or "knowledge workers," in the modern parlance -- have had two productivity peaks in their workday: just before lunch and just after lunch. But since the pandemic, a third and smaller bump of work has emerged in the late evening. Microsoft's researchers refer to this phenomenon as the "triple peak day."

For the new study, workers allowed Microsoft to track their "keyboard events" -- a funny euphemism for sending emails or engaging with productivity applications on a work computer. While most people didn't show a third mountain of work in the evening, 30 percent did. They were working almost as much at 10 p.m. as they were at 8 a.m. Several underlying phenomena are pushing up this third mountain of work. One is the flexibility of at-home work. For example, parents of young kids might interrupt their workday or cut it off early for school pickup, dinnertime, bedtime, and other child care. This leaves a rump of work that they finish up later. Other workers are night owls who get their second wind -- or even their primary gust of creativity -- just before bed.

      I'm similar. My peak production hours are 7:00 am to 7:30 am, If there's anything urgent, and maybe 4:00 pm to 6:00 pm, because once I get going I keep going. But anything much after 6:30 or so comes with a big productivity dropoff, and by 9:00 I'm getting ready for bed.
      But the TFA says productivity, but what was measured was "keyboard events". So I'm not really confident that they're measuring productivity at all.

    9pm-11pm are my peak hours by far. Often get the same amount of work done as I do the rest of the day. Not sure why, but I'm guessing for many of the reasons listed. Kids are in bed. I know I won't be disturbed by other employees. It just works for me.

      I wouldn't go so far as to call them my peak hours, but I do usually get a nice bit of energy in the late evening. But I have no intention of spending that time working if I can help it. The reason I have a job is to support my life, so any job that doesn't leave me any energy to invest in myself is one I'd want to leave as soon as possible.

    So they can start the next day. Doing your email takes about an hour or two a day when you work in a professional capacity. It's not difficult or mentally challenging work so you can do it at the end of a long tiresome day.

    The bigger problem here is that something that used to be part of your day job is now just one to two hours of free work for your employer you do every night before bed.

    I used to wonder how it was that a country like America could work more hours than the Japanese and now I know. We need to do something about the cult of work. As we work longer hours and harder and become more productive it's depressing everybody's wages. Which leads to us having to work longer hours to make the same amount of money which in turn leaves the more productivity and more depressed wages. There's some reduction in productivity when you're overworked but it's not 100%. And the important thing is every bit of productivity you can squeeze out of your employees in excess of 40 hours means you get closer and closer to being able to hire one less employee.

      I write those hours down... Don't you?

      I do a lot off hours at the moment... I'm inside my three months notice... I'll probably give my superiors the middle fingers a week earlier like this.

      You know what helps my productivity most of all? Not giving a fuck and finally doing what is right without asking left and right if it's okay. No longer "Customer dearest would it be alright to take down your system for 15 minutes to patch this possibly bankruptcy level security issue? Pretty please?" No. "Yo. Your systems will be down for half an hour this evening. Deal with it."

      Our environment hasn't been this well-groomed in years. All thanks to me and my middle-finger-attitude.

      • I write those hours down... Don't you?

        No because my manager doesn't helicopter me, I don't get paid by the hour, and don't have short term memory issues. Yes it's 11am right now. No I'm not "on the clock", that's what the evening is for.

    • For me, going through emails is something that doesn't require an extended period of uninterrupted concentration. In fact, it's 100 different emails, so interruptions hardly matter for that task. The perfect task to do while waiting for a meeting to start or for something to load / connect.

      What I would choose to do after ordinary work hours are things that mean I need to not be interrupted for an hour or more.

      But then, I'm wide awake at 8PM or 9PM. Maybe you aren't. That ties in to ...

    Previous studies have shown that productivity depends on long, uninterrupted work periods and the article summary suggests that also accounts for the recent increase in late-night productivity.

    Here is a trick: Go to bed at 9:00 and start work at 5:00 am in the morning. For me, that gives me a long and uninterrupted interval for work until my meetings start around noon.

    Also, if you like to go jogging in the mornings, that's a perfect time to avoid traffic, then start work at 6:00 instead.

    The 9-5 Bankers hours, is a mostly unnatural phenomenon for humans.
    Traditional non-mechanized farming had farmers doing their work early in the morning, to around mid-morning, then they take time off, then go back to the fields in the afternoon - evening.
    Hunters do the most of their hunting, near dawn and dusk.
    The traditional bankers hours, were there to help service the people during their down times, which also included shops and schools.
    As the economies of the world moved away from a Farming and Hunting Gathering life style. the Bankers hours still remained common, while the reason for its existence is now antiquated. As we have shoved nearly all the economy in the 9-5 time, so shopping and banking is no longer convenient times, and said stores need to be open longer hours and more days a week.
    During Dawn and Dusk is when humans are at their peak.

    • said stores need to be open longer hours and more days a week

      Stores used to be open late, and then they cut back to sanitize during COVID, and have yet to return to their normal hours. Banks used to be open on weekends and now due to the "labor shortage" are cutting out those hours. Pharmacies, too, are cutting back there hours due to the same "labor shortage".

      This factor alone IMO is reason for the 9pm work hour.
