Sabbatical leave is generally granted in Universities to members of teaching faculty as well as in research institutions to scientists to pursue higher studies or doing some research independently elsewhere in cognate fields without severing the employer-employee relationship with or without salary depending on the nature of the purpose. Now a days some MNCs also include sabbatical leave in their leave policy so that key employees do not leave them but rejoin with better knowledge and new ideas which can add to the growth of their business.
