27 Miss. Code. R. 110-5.4.11
An individual may be employed by more than one state agency or by a state agency and an institution of higher learning in two part-time positions, or one full-time and one part-time position. Policies, rules, and procedures governing appointments shall apply.
Under Fair Labor Standards Act (FLSA) regulations, the State of Mississippi is considered to be one employer. Therefore, eligible (non-exempt) employees who work for two entirely different agencies in state government in the same workweek are considered joint employees and must be paid overtime or must be provided compensatory time off for a combination of hours worked in excess of forty (40) hours. Overtime payment or provision of compensatory time should be computed according to current FLSA rules issued by the U.S. Department of Labor.
