A sabbatical (from the Late Latin sabbaticus, from the Greek sabbatikos, from Hebrew shabbathon, i.e., Sabbath. ) is a rest from work, a hiatus. The concept of a sabbatical has a source in several places the Bible (Leviticus 25, for example), where there is a commanment to desist from working the fields in the seventh year. In the strict sense therefore, a sabbatical lasts a year. However, in recent times, a sabbatical has come to mean any extended absence in the career of an individual. In the modern sense, one takes a sabbatical typically to merely take a break from work or to fulfill some goal, e.g., writing a book or traveling extensively for research. Some universities and other institutional employers of scientists, physicians, and/or academics offer a paid sabbatical as an employee benefit, called sabbatical leave. Some companies offer an unpaid sabbatical for people wanting to take career breaks - this is a growing trend in the UK, with 20% of companies having a career break policy, and 10% considering introducing one.
