Father, thanks for highlighting the issue which is not isolated. The government is one of the worst culprits where NIS contributions are concerned. Some the years of non payments involve years when stamped cards were used and stored at the NIS. It strikes me as strange that even years when automatic deductions were made that such payments were not remitted. All is, however, not lost and the pensioner is right not to take the one time lump sum payment.
I thought that the Associate at the NIS, instead of rushing to pay the lump sum, should have advised the pensioner the courses open to him e.g Getting a letter from the Government agency where he worked as proof of employment. An appeal would be filled with the tribunal. After this he will get his benefits. I sympathize with the pensioner. He needs his pension to survive. He will also enjoy his back pay. Father, I know you are genuinely concerned, please assist this pensioner.
