27 Miss. Code. R. 110-2.1.1
Employees not otherwise excluded from the state service, with at least twelve months' continuous state service in an agency and who have not been assigned extended probationary status, shall have state service status. Mississippi Code Annotated §§ 25-9-127; -143. OSR will automatically update the status of employees who have completed the twelve-month probationary period.
Upon original appointment into state service, each incumbent shall automatically receive a status date the same as the hire date. This date reflects the beginning date of the incumbent's status in state service. The term "Probationary" will automatically be placed in the "Employee Status" field when the transaction is processed. Upon completion of twelve months of continuous state service, each employee shall attain state service status and the term "Permanent" will automatically be placed in the "Employee Status" field by OSR.
Once an employee has attained state service status, the status date shall remain the same on any requests for in-service movement except in the following cases: state service to non-state service; non-state service to state service; and litigated classes to state service.
Any request processed for in-service movement in the above-mentioned cases shall automatically reset the status and the status date of the employee to the effective date of the transaction.
