An employer shall not, during the Public Health Emergency and State of Emergency declared by the Governor in Executive Order 103 of 2020 concerning the coronavirus disease 2019 pandemic, terminate or otherwise penalize an employee if the employee requests or takes time off from work based on the written or electronically transmitted recommendation of a medical professional licensed in New Jersey that the employee take that time off for a specified period of time because the employee has, or is likely to have, an infectious disease, as defined in section 2 of P.L. 2005, c. 222(C.26:13-2), which may infect others at the employee's workplace. The employer shall not, following that specified period of time, refuse to reinstate the employee to employment in the position held when the leave commenced with no reduction in seniority, status, employment benefits, pay or other terms and conditions of employment.
