Americans are leaving paid time off on the table. 

A majority, 78%, of U.S. workers say they don't use all of their PTO, according to a new Harris Poll survey of 1,170 American workers.

People cited busy schedules, heavy workloads and a persistent "pressure to always be available" as the biggest impediments to taking more time off.

It doesn't help that flights, hotels and other vacation amenities have gotten more expensive. Overall, travel costs are up 15% versus 2019, according to a NerdWallet analysis.

Still, paid time off is a sought-after benefit among U.S. workers, with 48% saying they would rather have more PTO than a higher salary, the Harris Poll found.

To stave off burnout and improve employee retention, some companies — many of which are in the travel industry — are handing out four-figure stipends for employees to see the world. Others are offering to help offset the cost of employees' vacations, either with flight or hotel credits.
