Section 169-A. One day of rest for state employees

No person employed by
  the state shall be required to work more than six days in  any  calendar
  week,  except in cases of fire, riot, flood, famine, pestilence or other
  cases of emergency endangering life or property; provided, however, that
  any such person, upon his own request and with the approval of the  head
  of  the  department  or  institution  in  which  he  is employed, may be
  permitted to work one additional day in any calendar week for  not  more
  than  seven calendar weeks and be allowed continuous days free from duty
  equivalent to the number of additional days so worked. No person  shall,
  by  reason  of  the provisions of this section, receive any reduction in
  the total weekly compensation paid him. This section shall not apply  to
  officers and members of the state police force.
