In business, the term boiler room refers to an outbound call center selling questionable investments by telephone. It usually refers to a room where salespeople work using unfair, dishonest sales tactics, sometimes selling penny stocks or private placements or committing outright stock fraud. A common boiler room tactic is the use of falsified and bolstered information in combination with verified company-released information. The term is pejorative: it is often used to imply high-pressure sales tactics and, sometimes, poor working conditions.
