Something Else

Going postal is an American English slang term, used as a verb meaning to become extremely angry, possibly to the point of violence. The term derives from a series of incidents from 1986 onwards in which United States Postal Service (USPS) workers shot and killed managers, fellow workers, and members of the police or general public. Between 1986 and 1997, more than 40 people were killed in more than 20 incidents of workplace rage. Following this series of events, the idiom entered common parlance and has been applied to murders committed by employees in acts of workplace rage, irrespective of the employer; and generally to describe fits of rage in or outside the workplace.
Homicide statistics show that Postal Service employees are no more likely to "go postal" than are other American workers. Researchers found that the homicide rates per 100,000 workers at postal facilities were lower than at other workplaces. In major industries, the highest rate of 2.1 homicides per 100,000 workers was in retail. The next highest rate of 1.66 was in public administration, which includes police officers. The homicide rate for postal workers was 0.26 per 100,000. The Most dangerous occupations: taxi drivers, with a homicide rate of 31.54 per 100,000 workers.
That wasn't unusual to bring up was it?
