| I were going to say this, but found it in the Results / Conclusions part (nice link!). So to paraphrase: Results: Working >40 to 50 hours per week and >50 hours per week were significantly positively associated with work productivity in univariate analysis. However, the significant association no longer held after adjusting for work engagement. Work engagement was positively associated with work productivity even after controlling for potential confounders. Working hours were not significantly associated with work productivity among those with high-work engagement or among those with low-work engagement. Conclusions: Working hours did not have any significant associations with work productivity when taking work engagement into account. Work engagement did not moderate the influence of working hours on work productivity, though it attenuated the relationship between working hours and work productivity. In my personal experience of workplace since 90's, whenever you have the chance to "level up", work a bit extra to gain a bit more progress and experience, it's absolutely worth it. If you don't gain anything by it or have no meaningful work to do (ie. process-related tasks and projects), it is worth more to you to leave work for another day. I've become sensitive enough I can feel the stress begin to build at the end of the day, and know which day is worth to leave work (most days), and which rare day is worth more to you to stay a bit longer just to follow that flow out to its end. Anything new after 3PM can wait to next day. Your mind will anyways work it out in the background if it's important somehow. |
But in the vast majority of cases a lot of hours worked cannot be sustainable or beneficial to the employee.
