State employees; remove requirement to use one day of personal leave before using major medical leave.

HB 138 removes a requirement that Mississippi state employees must use one day of accrued personal leave (or take unpaid leave if they have none) before accessing major medical leave for serious health needs. This change directly affects all state employees covered under Mississippi's leave policies, including those with medical conditions requiring extended care. The bill modifies existing rules to allow employees to immediately use major medical leave without first exhausting personal leave days. It does not alter the accrual rates for either leave type or the eligibility criteria for medical leave. The policy change simplifies access to medical leave for employees and their immediate families during health crises.
