Jobcentre Plus
The Jobcentre Plus service (and its forerunners the Social Security office, Unemployment Benefit office and Jobcentre/Labour Exchange) have featured in all forms of popular culture, often depicted in a general way to suggest poverty or unemployment. In the 1980s in particular, the Social Security office was frequently used as shorthand for the British recession.
