The requirement that an employee of a health care facility accept work in excess of an agreed to, predetermined and regularly scheduled daily work shift, not to exceed 40 hours per week, except in the case of an unforeseeable emergent circumstance when the overtime is required only as a last resort and is not used to fill vacancies resulting from chronic short staffing and the employer has exhausted reasonable efforts to obtain staffing, is declared to be contrary to public policy and any such requirement contained in any contract, agreement or understanding executed or renewed after the effective date of this act shall be void.
