YOUR WORKING ENVIRONMENT IS KILLING YOU!

Many of us spend plenty of our time at work, but rarely give much thought to how our environment might be affecting us.

Open offices could be making you unproductive and unhappy. A 2011 review of studies examined the effects of various types of office environments. It found that open offices can have a negative impact on workers when it comes to focus, efficiency, creativity and job satisfaction12. However, a 2013 study found that employees with private offices were more satisfied at work.

A noisy workspace could be killing your concentration because of phones ringing and colleagues chatting, typing and moving around. These noises are the “enemy of focus” and meaningful time is lost.

Your working environment could be upping your stress levels. A recent Monster.com poll found that 42 percent of U.S. workers have left a job due to stressful environment. It also found that 61 percent of American workers believe that work stress has been a cause of illness.

Working in Germany

Juan Morales is 19 years old. He has left his parents who live on a small farm in Spain. He now works in a car plant in Germany. Every 30 seconds, a car rolls past Juan on a production line. Juan must dive into the open trunk of the car and tighten (拧紧) two bolts (螺栓). Two times a minute, Juan must tighten these same two bolts on every car that comes by on the line.

Juan has done this job on every working day for six months. When he goes back to his rented room at the end of each day, he is very tired. Sometimes he will go out for supper with other Spanish workers. But supper in a restaurant costs money, and Juan is trying to save money. Often he just cooks supper in his home and eats alone.

Ju_an is there because there is plenty of work in Germany more work than there are workers to fill the jobs. Because of this, few German workers have to take a job like Juan's. But people from some other countries are eager to do the work because wages are high in Germany.

d puts half his pay in the savings bank. Then he sends about a quarter of the money back home. The rest is enough to live on if he is careful.
