Can an employer object to an employee being sworn to a jury?

No, no, no. If an employee is selected to be sitting juryHowever, his employer cannot oppose it.

This is a civic obligation that also applies to the employer. The employer's agreement is therefore not necessary.

The employee must notify his employer by giving him a copy of his summons as soon as he has received it.

Employers are prohibited from penalizing employees who are absent from jury duty (whether or not they are disciplinary sanction, a dismissal, or discriminatory measures).

During the employee's absence, his employment contract shall be suspended.

He receives no remuneration from the employer.

However, the employee shall be entitled to a compensation for loss of professional income (on application and on justification to the Assize Court).
