A domestic worker, domestic, or servant is one who works within the employer's household. Servants are distinguishable from serfs or slaves in that they are compensated, that is, they must receive payment (and, following labour reforms in the 20th Century, benefits) for their work. They are also free to leave their employment at any time, although socio-economic conditions and laws relating to working in a foreign country may make that difficult.
In large households, there can be a large number of domestic workers doing different jobs, often as part of an elaborate hierarchy.
A butler is a senior domestic worker, whose duties traditionally included handling the wines of the household and some management of the other servants. Female domestic workers are often called maids.
Domestic workers perform typical domestic chores such as cooking, ironing, washing, cleaning the house, buying foods and drinks, accompanying the female head of the household for grocery shopping, taking the family dog for a walk, and taking care of the children. In some countries, maids replace the role of a nurse in taking care of the elderly and people with disabilities. Maids often are expected to work at least fifteen hours per dayfound: http://en.wikipedia.org/wiki/Domestic_worker
