.An employee  of a Swiss factory killed three people, while injuring seven others during a shooting spree.  

This marks another story of a former employee shooting and killing his coworkers happened, this time in Switzerland. 

"The workers were eating a snack in the cafeteria during the morning, and there was a massacre," said a man quoted by the Swiss news website 20minutes, who had phoned the factory to check on the welfare of his father.

The 42-year-old  man worked at a factory for ten years before the shooting. There were rumors of cuts to be announced. It is not known if the man feared for his job or there was another reason behind this killing.

The chief executive of Kronospan, Maura Capozzo denied any of the cuts that were rumored.

The killer's name has yet to be released, but Capozzo described him by telling Reuters, "One almost didn't see or notice him."

Names of the victims haven't been released yet either, but fellow employees are expected to be the ones deceased.

With so many work places becoming kill-zones for people, the term "going postal" has been used to describe when somebody becomes uncontrollably angry and takes out their frustration at work, often in violence.

As recently as September, Andrew Engeldinger claimed six lives in Minneapolis, Minnesota.  He was fired that day and decided to come back and take his revenge out on the company, Accent Signage Systems Inc.

Engeldinger went in, killing employees, a UPS driver on the premises and the owner of the company. Others were wounded and hospitalized.

Police found Engeldinger dead in the basement of the building.

The family of Engeldinger said he had a mental illness, but wasn't an excuse for his actions.

Going postal has become a repetitive action and not just in the United States.

Switzerland has one of the highest rates of gun ownership in the world, with an estimated 2.3 million firearms owned by the country's eight million people, though gun attacks are rare.

Swiss men are obliged to do military service once they turn 18 and are issued an assault rifle or pistol. These guns are supposed to be left at their respective homes.

Until recently, many kept their weapons even after completing their military service, forcing the rules be fixed.

Homicides in Swiss rank second in Europe, according to Emma Jay Kirby, who recently investigate the subject.

This killing adds to that statistic for a list no country want to be high on.
