D1c16 – Is an employee who resigned following a change to his employment contract entitled to a severance allowance?

Yes.

It has been confirmed in the case law that termination of an employment contract deriving from an employee’s refusal to accept a detrimental change of an essential clause of the employment contract which has been notified to him by the employer constitutes a dismissal giving rise to application of the legal provisions governing the rights of dismissed employees, including Article  L. 147-7 relating to severance allowances.
