In our view, however, this fact does not preclude the possibility that a county may share co-employer or joint employer status with the courts. While we have found no ease which directly implicates this issue in the factual scenario we confront here (that is to say, which involves the narrow question of the division of responsibilities between counties and courts vis-a-vis judicial personnel), we draw some guidance from eases which have found joint employment status when two entities exercise significant control over the same employees.
