A domestic helper is a person who works within the employer's household. Domestic helpers perform a variety of household services for an individual or a family, from providing care for children and elderly dependents to housekeeping, including cleaning and household maintenance. Other responsibilities may include cooking, laundry and ironing, shopping for food and undertaking other household errands. Such work has always needed to be done but before the Industrial Revolution and the advent of labour saving devices, it was physically much harder.
