Sabbaticals are being offered to employees in an increasing variety of lengths and styles. Some companies offer this benefit after as few as six months’ service, although it’s more common for employees to qualify after five or seven continuous years with a company. They’re offered in durations from a week to a year. These periods of paid time off are often used for travel, volunteering, education, with family, or a combination of several of those.

The intention is to help the employee reset and come back rejuvenated and refreshed–as an enhanced worker (not to mention human being). The examples of how people used their time off from the following 21 companies offering paid sabbaticals suggest they are successful in those goals of self-improvement and refreshment.
