My Saba (grandfather in Hebrew) started working in the mailroom after his retirement so that he had something to do. Between 1945 and 1950, my grandfather was a leader of a political movement (Hashomer Hatzair) that prepared Jewish people who survived the war for life in Israel and on kibbutzim.
When he came to Eilon, he was a factory worker by day and a kibbutz Secretary General by night. He was responsible for organizing the kibbutz’s social life and making sure that it all worked out fine. He was responsible for the social justice and the discipline. He was then recruited to work as a politician in the Left wing party that the kibbutz belonged to called Mapam. After that, he lived in Tel Aviv for many years but came to visit the kibbutz and his family at least twice a week. Every Tuesday and Friday or Saturday. He worked as a politician until he retired and only then did he become involved with the mailroom.
He was 75 when he retired from being a politician. After that, my grandfather worked in the mailroom every morning. He walked up a large hill every morning at 6am to sort the mail. His days ended at noon and was able to go back to my grandmother and spend the day with her. My grandfather never retired from working in the mailroom. He worked there until he died. Even when we were worried about him making the walk alone up to the mailroom when he got to an old age, he did anyways.
