Assédic is the partial acronym of "Association pour l’emploi dans l’industrie et le commerce" (transl.
Created in 1958, it was a French agency that collected and paid unemployment insurance contributions.
People living in France and needing unemployment support between jobs must keep the job contract, all payslips (which show all salary figures, and deductions), the "Certificat de Travail", which is proof that you have in fact worked at that enterprise, and an "Attestation de L'Employeur", designed specifically for Assédic, that shows all mathematical details of the employee's company work record.
Assedic bases its allocations to an individual's revenue on the amount of money earned over a previous period, a percentage of which is calculated and awarded on a daily (compiled in the monthly allocation) basis.
Therefore, if a person, over a two-year period, were to lose their job through means other than resigning voluntarily, or being dismissed for serious breaches of contract or criminal behaviour, they are entitled to a certain number of days (broken down into hours for calculation purposes) paid at a certain rate per day.
