Can I refer to Article 218 of the Labor Code and pay half salaries for the period during which the facility is closed?

In the present case Art. 218 of the Labour Code is not applicable.
In the case of a declared state of emergency, the employer may, by order, suspend the work of the enterprise, part of the enterprise or individual employees for the whole period or part of it until the state of emergency is canceled. The employer is obliged to pay the gross salary to the employee for the duration of termination of employment.
