In a 2007 report about public and private sector approaches to sabbaticals, researchers at the University of Illinois found that “many corporations consider the benefits of sabbaticals so self-evident that they forego the expense of documenting them.” A stronger endorsement is hard to imagine.

However, among private employers — especially law firms — the popularity of sabbaticals tends to wax and wane, depending on broader economic trends. When times are busy, a partner deciding to take time out from client work may not be a popular move, however much they would appreciate the break.
