I think working more hours per day would definitely depend on the field a person is in. In healthcare, I don't that 12 hour shifts are a very good idea, especially with many facilities being understaffed as far as nursing goes. I think they should go back to the basic 8 hour work day so that the healthcare professionals are more rested.
In other fields, a longer work week may be beneficial. I thought a study done several years ago showed that Americans worked too many hours per day which was detrimental and also, that Americans took fewer vacations in comparison to European countries. Does anyone else remember hearing about that? In the study, it showed that with longer working hours, the quality of the products Americans produced were inferior to other countries where the employees worked fewer hours and took vacations more often.
Let me know if any of you are familiar with this study.
