A sentence of imprisonment under the Department of Corrections suspends all the civil rights of the person so sentenced, except the right to make employment contracts, during confinement under said sentence, subject to the approval of the Director of the Department of Corrections, when this benefits the vocational training or release preparation of the prisoner, and forfeits all public offices, and all private trusts, authority or power, during the term of such imprisonment. Provided however, such persons during confinement shall not be eligible to receive benefits under the unemployment compensation law.
