Working time is the period of time that an individual spends at paid occupational
labor. Unpaid labors such as personal housework or caring for children/pets are not considered part of the working week. Many countries regulate the
work week by law, such as stipulating minimum daily
rest periods, annual
holidays and a
maximum number of working hours per week. Working time may vary from person to person often depending on location, culture, lifestyle choice, and the profitability of the individual's livelihood. For example, someone who is supporting children and paying a large mortgage will need to work more hours to meet a basic
cost of living than someone without children of the same
earning power. As fewer people than ever are having children choosing
part time is becoming more popular.
