Studies Show Working Overtime Is Basically Pointless

August 26, 2022

If I asked a room full of men to raise their hand if they work more than 40 hours per week, nearly every hand would go up. 

If I asked them to keep their hand raised if they work more than 50 hours per week, I imagine only a small minority of the room’s hands go down.

If I kept going, hands wouldn’t start going down until we hit the 60+ hours per week mark. (See here, here, and here.)

If you’re like me, you can’t even answer that question because the work day blends seamlessly with the rest of the day. We don’t even know what to call the part of the day when we’re not working. We just call it the “rest of the day” or “after work”.

It’s a sad reality, but somehow we’ve come to believe it’s not only okay to work all the time, but that successful people – especially successful men – should be putting in endless work hours. After all, opportunity never sleeps, right? As it turns out, opportunity does sleep. It also takes breaks, and it knows when it’s time to turn work off; and it prefers if you do too. 

Researchers have found that putting in all those extra hours of work, specifically over 50 hours, can end up being a waste of time from a productivity standpoint.

Here’s what the researchers say:

“Productivity drops immediately upon starting overtime and continues to drop until, at approximately eight 60-hour weeks, the total work done is the same as what would have been done in eight 40-hour weeks.” – IGDA

So if 60 hours is too much, how many hours per week should we strive for? I thought you might ask…

Another study found that when people worked more than 50 hours, output per hour started to fall. – Economist

Around 50 hours is the cutoff according to research. Here’s what that looks like: 6 am to 4 pm, 7 am to 5 pm, 8 am to 6 pm, or break it into multiple shifts if you prefer, whatever works best.

If that sounds like it’s not enough time to get everything done, you might just need to change how you work in order to maximize productivity. For example, studies have found that working for 1-2 hours, then taking a 20-30 minute break, keeps your brain fresh and enables you to accomplish more in less time. The fancy word for this is “Ultradian Rhythm“.

The point to all this is, your spouse is right, you do work too much. 8-10 hours a day is reasonable, and you won’t get much more accomplished by working over that.

And let’s be honest, we’re going to push it a bit over the 50 hour mark on any given week. I mean, we’ll take a cut in productivity in order to pump out a few extra hours on the weekend, right? So throw in a few hours on Saturday to wrap up the week, but draw the line there.

DO give yourself at least a day and a half a week to just rest (my rest time is Saturday afternoon and all day Sunday). Turn it all off and spend time in the real world, with your family, friends, whatever. For goodness sakes man, do some yard work. It’s good for the soul.

And next time 5 o’clock creeps up and you think – “Okay, just one more thing and I’m done…” – don’t do it. It’s (scientifically) not worth it.
