A great challenge today, both an occupational one and one that threatens the lifestyle, is the long working hours - often not paid.
In many companies, the workers are expected to work up to 60 hours a week! They have to do it, so that the company is successful and because they are threatened with loosing their jobs.
Long working hours are bad for the lifestyle - they can cause health problems and make social life hard, but they are also bad for the work the workers do, as they can suffer a burnout and actually perform their work worse than if they'd been working less hours.
