CA SB850

Requires employers in grocery stores, restaurants, and retail establishments to provide employees with work schedules at least 7 calendar days in advance.

Mandates "modification pay" compensation when employers cancel, move, or add shifts with less than 7 days' notice: one hour pay for 24-72 hours notice, or half the shift hours (2-4 hours minimum) for less than 24 hours notice.

Requires modification pay equal to half scheduled hours for on-call shifts where employees are required to be available but not called in to work.

Exempts schedule changes from modification pay requirements for emergencies, utility failures, acts of God, other employees' absences, disciplinary actions, mutual shift trades, and mandatory overtime.

Establishes Labor Commissioner enforcement authority with administrative penalties up to $4,000 per violation and authorizes civil actions for employees, the Attorney General, and employee organizations to recover unpaid modification pay trebled, liquidated damages of $50 per day per person, attorney's fees, and costs.
