Cela force les deux parties à tempérer leurs demandes, avec raison, parce qu'elles savent que si elles présentent une proposition trop étrange, l'arbitre choisira celle de l'autre partie.
If all the parties are arguing about is a 50 cent pay increase the employer will come to final offer selection with, say, 25 cents and the employee will come with, say, 75 cents and the arbitrator will choose one or the other. That forces both parties to temper their demands with reason because they know if they put forward too outlandish a position the arbitrator will choose the other party.
