In a leafy and affluent neighbourhood in the northern suburbs of Madrid, the school run swings around. Women dressed in maid’s scrubs that are hues of clinical pink, purple and blue – rush around collecting other people’s children, walk other people’s dogs, take out other people’s rubbish and fetch other people’s groceries. Their uniforms mark who belongs to these security-patrolled communities, but the reality that exists beyond their scrubs is one of exploitation; long hours, low wages, limited legal protection and in some cases abuse.
