No-Vacation Nation: Why Americans Feel That PTO Is NSFWA look at why U.S. workers are afraid to take time off.

Let's get real: You need a break.

Studies have shown that time off from work is great for your body and your mind. Problem is, no one's taking it. A survey of more than 1,300 U.S. employees and senior business leaders, conducted by GfK Public Affairs & Corporate Communications for Travel Effect and the U.S. Travel Association, shows that Americans are increasingly stressed at work but aren't taking the breaks they've earned. Despite acknowledging the benefits of downtime, 41 percent do not plan to use all their paid time off (PTO) this year.
