I work in several workplaces, to which of my employers am I to give the military authorization, in order to receive a reserve service benefit?

You must give the military authorization to only one employer (preferably the main employer), and he will pay you the benefit for the work you do for him. In order to receive the benefit due to you with respect to your employment in other workplaces, you must submit a claim for benefit supplement to one of the branches of the National Insurance Institute and attach the last three wage slips preceding the month of reserve service from each employer, as well as a photocopy of the military authorization.
