The concept of the sabbatical is based on the Biblical practice of shmita, which is related to agriculture. According to Leviticus 25, Jews in the Land of Israel must take a year-long break from working the fields every seven years.
A "sabbatical" has come to mean a lengthy, intentional break from a career.
Some universities and other institutional employers of scientists, physicians, and academics offer the opportunity to qualify for paid sabbatical as an employee benefit, called sabbatical leave. Some companies offer unpaid sabbatical for people wanting to take career breaks; this is a growing trend in the United Kingdom, with 20% of companies having a career break policy, and a further 10% considering introducing one.
In British and Irish students' unions, particularly in higher education institutions, students can be elected to become sabbatical officers of their students' union, either taking a year out of their study (in the academic year following their election) or remaining at the institution for a year following completion of study. In Israel, school teachers and preschool teachers are entitled to take a sabbatical leave.
