We are a CAS school and have two separate sets of benefit rates (long story). Our endowed college rates include sabbatical leaves in the employee benefit rate. Our policy is at https://www.dfa.cornell.edu/sites/default/files/vol6_2_1.pdf, and sabbatical leaves are discussed on page 20. Feel free to give me a call for more details.
