Whether you volunteer, or are assigned, to the SAL, this is a temporary leave of absence for the period of April 1 – May 31, 2020. While on leave you retain your seniority. Your benefits remain intact (Health, Dental, Basic Life, Voluntary Life, Long-Term, and Short-Term Disability insurances). But note that you’re still responsible for your share of the health insurance premium, so you’ll need to reach out to HR to make arrangements for paying that.
