In order to validly terminate employment on this ground, Section 8, Rule I, Book VI of the Omnibus Rules Implementing the Labor Code requires that:
Section 8. Disease as a ground for dismissal. — Where the employee suffers from a disease and his continued employment is prohibited by law or prejudicial to his health or to the health of his co-employees, the employer shall not terminate his employment unless there is a certification by a competent public health authority that the disease is of such nature or at such a stage that it cannot be cured within a period of six (6) months even with proper medical treatment. If the disease or ailment can be cured within the period, the employer shall not terminate the employee but shall ask the employee to take a leave. The employer shall reinstate such employee to his former position immediately upon the restoration of his normal health.
