The airline, which is struggling to compete with global rivals, announced job cuts after failing to convince its pilots to work longer hours on same salary.
The airline’s human resources manager Xavier Broseta and the head of long-haul flights Pierre Plissonnier had to flee from the angry workers, with their shirts torn off.
Seven people, including a security guard, were injured in the incident.
French President Francois Hollande said, “Social dialogue matters and when it’s interrupted by violence, and disputes take on an unacceptable form, it can have consequences for the image and attractiveness” of the country.”
A criminal investigation has been launched into the incident.
