We need vacations but don't take them

More than 60% of us feel less stressed out after a vacation, yet more than half of all workers don't take their allotted vacation days, according to a Westin Hotels & Resorts study. Why? Because they are too worried about their job security and the economy.

Many companies have adopted a "use it or lose it" policy as it relates to promised time off and 58% of the hotel chain's study respondents said they were more in need of a vacation than they were last year. Yet 64% of them canceled vacation plans due to work worries.

The cancellations come even as workers pine for the benefits of time away. More than 67% feel healthier on vacation and 64% said they slept better. More than half of those surveyed said taking a vacation contributes to a stronger marriage.
