Working Too Many Hours Can Backfire

American working hours have progressively increased, but that increase has not necessarily caused workers to increase their output. More the 50% of U.S. workers routinely put in more than 40 hours per week, working more than 46 hours per week on average (Saad, 2021). However, employees’ productivity sharply falls after working 50 hours per week. This decrease in productivity is so strong that an employee working 70 hours per week has almost no difference in output than an employee who works 50 hours per week (Pencavel, 2014). 

Technology, now a mainstay in our society, allows for people to work anywhere and anytime. In fact, almost 50% of employees say access to technology has significantly increased their working hours since supervisors can now communicate with employees past their time physically in the office (Purcell & Rainie, 2019). It is important to set boundaries and limit how many working hours are being added to employees’ days and to know what their working hours are, or when they should be expected to respond should members on the same team have varying hours.

At a Glance

  • More than 50% of U.S. employees work more than 40 hours per week, working more than 46 hours per week on average 
  • Long hours are associated with higher turnover and absenteeism
  • Technology increases working hours for almost 50% of employees, as people are always connected
  • Productivity falls after working a 50-hour workweek 
  • Productivity decreases so much that an employee working 70 hours has almost no difference in output than an employee working 50 hours per week 
  • This is an important reason to be mindful of work-life fit
