A new survey found that almost half of Americans don't take all of their paid vacation time, partially out of fear of losing their jobs.

Fox affiliate WGHP reported:

The study, an initiative of the US Travel Association, is entitled “Overwhelmed America: Why We Don’t Use Our Paid Vacation Time.” According to study researchers, 40 percent of American workers will leave paid vacation time on the table. Even more revealing are the reasons respondents gave for not taking the paid vacation time. The four reasons cited the most are the dread of returning from a vacation to piles of work (40 percent), the belief that no one will be able to step in and do their job for them while they’re gone (35 percent), not being able to afford it (33 percent) and the fear of being seen as replaceable (22 percent).

On The Five, Dana Perino said that in today’s competitive society, some people may fear taking time off because they risk being usurped by someone younger and more energetic.

Perino added that managers need to make employees feel comfortable about taking time off.
