English to French Law/Patents Law: Contract(s) droit du travail

For example, since Employee will have benefits under French law (which the establishment will pay for) the parties will need to harmonize and equalize the total compensation and benefits provided under both contracts, so that there is not an unfair or double dip. Under the French Contract, the establishment and the Employee will agree to pay all required social charges as determined by French law and the cost of such social charges shall be offset against benefits and compensation provided under the US Contract.

Je ne vois pas bien à quoi ce "dip" fait référence. Merci de votre aide éventuelle.
