Minn. Stat. § 43A.183
(a) Each agency head shall pay to each eligible member of the National Guard or other reserve component of the United States armed forces an amount equal to the person's salary differential for each month or portion of month that the person is ordered to serve in active military service. The person's salary differential is calculated as the difference between:
(2) the person's monthly base pay in active military service.
This payment may be made only to a person for whom the amount in clause (1) is greater than the amount in clause (2). Payments must be made at the intervals at which the member received pay as a state employee, except that any back pay due under this section may be paid as a lump sum. Payment under this section must not extend beyond four years from the date the employee reported for active service, plus any additional time the employee may be legally required to serve. An eligible member of the National Guard or other reserve component of the United States armed forces may apply for the pay differential benefits authorized under this section prior to, during, or following the person's active military service on or after May 29, 2003.
(d) For purposes of this section, the term "active service" has the meaning given in section 190.05, subdivision 5, but excludes service performed exclusively for purposes of:
(f) The agency head must periodically inform in writing all agency personnel who are or may be members of the reserve component of the United States armed forces of the benefits provided under this section and of the procedures relevant to securing those benefits, including, but not limited to, any procedures regarding the continuation and discontinuation of any optional deductions. It will suffice to meet this requirement if the agency head posts the information on the agency Web site in a highly recognizable manner that can be easily found and understood by the employees to whom it might apply.
Upon being ordered to active duty, the employee must notify the agency head of that order in a timely manner and must provide to the agency head the name of and contact information for the employee's designated attorney-in-fact under a power of attorney. Prior to the commencement of the employee's military leave, the agency head must ensure the agency's receipt of that information and immediately convey that information to the commissioners of finance and employee relations, including any subsequent change in that designation by the employee. When communicating with the employee during the person's military leave, the agency head and the commissioners of finance and employee relations must immediately provide a copy of the communication to the employee's designated attorney-in-fact. Those officials must also honor requests for information or other appropriate directives from that designee on behalf of the employee during the employee's military leave.
(h) This section does not apply to a judge, legislator, or constitutional officer of the executive branch.
