Business travelers are accustomed to the usual travel burdens: delayed flights, missed connections, hotel s reservation mismanagement. But those situations can, for the most part, be easily overcome and rarely put employees at risk of physical harm. Terrorist events, natural disasters and rogue riots can, however, and many fly abroad for work are concerned about this.

A recent study by Europ Assistance USA found that 31% of international business travelers are concerned for their personal safety. The study identified additional concerns and experiences of these travelers, as well as their level of preparedness. According to the study, half (51%) of the respondents experienced a medical need while traveling, with the 55% falling ill and 24% not sure they could obtain a prescription refill. One in two experienced a national disaster, while nearly a third (28%) encountered personal safety or security issues.

“With recent events such as the earthquake in Japan, political unrest in the Middle East and the ash cloud in Iceland, it’s an unpredictable and potentially risky world out there for business travelers,” said Glenn Maykish, vice president of sales and marketing for EA USA. “Understanding employee experiences and fears can help organizations better serve and protect their valuable employees while away from home.”

The study also offered up a useful infographic, helping to illustrate the findings.
