In today's industrialized societies, the majority of parents work full time while caring for and raising their children and managing household upkeep, trying to keep a precarious balance of fulfilling multiple roles as parent, worker, friend, & child. Increasingly demands of the workplace such as early or late hours, travel, commute, relocation, etc. conflict with the needs of being a parent. At the same time, it is through work that people increasingly define their identity and self-worth, and which provides the opportunity for personal growth, interaction with friends and colleagues, and which provides the income and benefits on which the family subsists.
