In unusual circumstances, not covered by other policies, the College may grant a leave of absence without pay to regular full-time faculty on ongoing appointments. Whenever possible, reasonable advance notice should be given. Leave will not be approved retroactively to cover a prior period of absence. A request for leave should be presented first to the department chair and Provost, and then to the Human Resources Office for approval. If such leave is granted, arrangements must be made with the Human Resources Office regarding any continuation of insurance coverage during unpaid leave.
