"Nevada Senate Bill 196, which provides for paid sick leave to employees of private employers, works against large employers in several ways, including: [1] a lack of guidance on eligible employee; [2] requiring the carryover of accrued sick leave, even when sick leave is front-loaded; [3] mandating the tracking of employees' accrued sick leave; and [4] providing no clear definition of who a family member is for purposes of care."
