To go to work is to experience a double edged sword. On one hand, your job leads you to have more money, which means you have more ways to spend and enjoy life. However, the flipside of your job is that it can truly make you want to kill yourself, or if you’re feeling murderous, your boss.

We all tend to feel this way from time to time, when the hands on the clock don’t go fast enough, when the work assigned to you keeps on piling up, when coffee no longer keeps you awake and functioning. As this is a common feeling experienced by masses all over the world, a research study was conducted into its reasons by economists in Denmark.

A study conducted by the people in University of Copenhagen and University of Purdue, Indiana, observed the health of Danish manufacturing workers from 1996 to 2006. What they found was an interesting correlation between the successful booms the manufacturing company faced with the sudden increase in the sick days the workers took from their job. It seemed that when the work piled up and work life became busier than before, the workers experienced greater health problems. Many started getting treated with depression, took pain medications as well as got into work related injuries at a higher rate.

The statistics indicated that if the companies export rose by 10%, the female workers were 2.5% more likely to get treated by depression and 7.7% increase in getting heart medications. Also, if the company experienced a 25% boom in their exports, it resulted in a 14% increase in sick leaves taken by men.

This vicious cycle, while worrisome for employers, at least now legitimizes the feelings of despair that many workers experience on a daily basis.
