https://docs.iza.org/dp8129.pdf https://docs.iza.org/dp8129.pdf Pencavel, "The Productivity of Working Hours", 2014 > The conclusion from the work presented in this section is that the output-hours relation is decidedly non-linear: below 49 weekly hours, variations in output are proportional to variations in hours; for those observations corresponding to 49 or more hours, output rises with hours at a decreasing rate and a maximum of output occurs at about 63 hours. Output at 70 hours differs little from output at 56 hours and, therefore, the HMWC’s recommendations about the innocuous effects for output of hours reductions are consistent with these estimates. Note that this is about manual labour, not knowledge work. I guess you think they are ignorantly damaging themselves. Not the OP, but I would think they are deliberately damaging their workers. The effect on the company itself is of no concern relative to that.
