    There's no way around it. Work is stressful. Most people go through points where their job is so taxing it feels as if it's consuming their entire emotional life. In some instances this situation can end in tragedy with an at-work suicide.

    In the U.S., suicide rates have increased considerably in recent years. Though workplace suicide trends have not been well documented, a new study aims to compare suicide rates in the workplace to those outside the job.

    The study, published in the American Journal of Preventive Medicine, found that between 2003 and 2010, 1,719 people in the U.S. committed suicide at work. During that same period, a total of 207,500 committed suicide outside the workplace. Overall, workplace suicide declined until 2007 and then began to increase. The researchers say that men are statistically more likely to take their life while on the job; men between the ages of 65 and 74 are at highest risk.

    "One hypothesis that may explain the increased suicide rate among specific occupations is the availability and access to lethal means, such as drugs for medical doctors and firearms for law enforcement officers," the researchers write in their study. "Workplace stressors and economic factors have also been found to be linked with suicide in these occupations."

    The study also observed that the global economic crisis in 2008 has impacted suicide rates for the worse. The national average workplace suicide rate for the years 2003 to 2010 was 1.5 per 1,000,000 workers.
