(1) to (4) may be sentenced additionally or alternatively to not to exceed 6 months suspension without pay from his or her employment by the institution if an employee, or suspension from enrollment in the institution if a student, or both if both an employee and a student. If the suspension is thus imposed, the institution shall not thereafter impose any other discipline upon the person for his or her connection with the unlawful assembly. Any period of suspension from employment by or enrollment in the institution already served shall be deducted by the court in imposing this sentence. Any period of imprisonment, whether or not the person is authorized under s. 303.08 to continue as an employee or student while imprisoned, shall count as a period of suspension from employment or enrollment or both hereunder.
