Ambulance chaser

A disrespectful name for someone (often working for a law firm) who seeks out the scenes of accidents to profit from those involved, usually by encouraging them to seek compensation.

e.g. my nephew wants to work in a law firm but the only job he has been offered is to encourage road traffic accident victims to take legal action and he doesn’t want to be an ambulance chaser.

The idiom uses the image of following an ambulance to get to the victim.
