The precious time after five can or should be used usefully as their own time to level up themselves for their own possible bright future, by which they can contribute both to companies and society.This should be helpful to the younger families with small children and in preventing the emergency medical system from its breakdown as well as cleaning up the companies that exploit their employees (e.g. through unpaid overtime, etc.).
