    """A Joint Health and Safety Committee.

    Most Canadian jurisdictions require workplaces above a certain employee
    count to maintain a Joint Health and Safety Committee (JHSC) with at
    least one worker representative and one management representative.
    The committee meets on a regular cadence to review hazards, incidents,
    and proposed improvements.

    A site can have one or more committees (e.g. when multiple buildings
    or shifts each maintain their own). Membership is tracked as overall
    members plus the specific worker and management representative subsets.
