Employers seem to appreciate their employees’ need for flexibility, according to a survey by Hudson on time off trends. More than three-quarters of the 2,082 U.S. workers who participated in the survey rate their employer favorably when it comes to allowing them to take extra time for personal matters, and virtually the same number also say their bosses are very or somewhat accepting if they need to stay home when they are under the weather.

While workers say their companies are flexible when it comes to providing time for personal matters, it appears many are hesitant to take full advantage of their allotted time off. In particular, among workers who get some vacation time, more than half do not use all of it, including 30% who say they take less than half of their days off. Plus, one in five workers only plan on getting away for long weekends this year without taking a full vacation. About one-third of workers have felt they had to play hooky and call in sick when they were not actually ill.

Nearly half of employees receive more than 11 vacation days each year, and nearly the same proportion indicate that their company designates a certain number of days for sick, personal and vacation time, while 28% are provided with a bank of time to use as they see fit.

When it comes to how managers and non-managers approach vacations, there are some distinct differences. For example, while more than one-third of managers check in with the office on vacation frequently, often daily, just 14% of non-managers do the same. In fact, while 34% of managers say their bosses expect them to be accessible on vacation, only 18% of non-managers indicate likewise. Furthermore, nearly 30% of managers return to the office more stressed than they were when they left, a situation true for only 16% of non-managers.

At the same time, managers anticipate taking more time this year, as 53% have plans to take both a full vacation and a long weekend compared to 44% of non-managers. On the other hand, non-managers are more likely than managers to expect to only get away for long weekends, 22% versus 18%.
