No law-enforcement officer shall be compelled to work extra duty without compensation as a penalty for a disciplinary infraction. No suspension for any period of time provided in departmental rules and regulations shall affect the law-enforcement officer's eligibility for pension, hospitalization, medical and life insurance coverage or other benefits specifically protected under the contract of employment. Suspension may affect time of pension eligibility by contractual provision or other statutory provision. Nothing herein shall prevent any law-enforcement agency from requiring reimbursement by a suspended law-enforcement officer of the officer's employee contribution to benefits during the officer's time of suspension.
