A kibbutz is a collective community in Israel that was traditionally based on agriculture and later also on other forms of production.
Kibbutzim attempted to rotate people into different jobs. One week a person might work in planting, the next with livestock, the week after in the kibbutz factory and the following week in the laundry. Even managers would have to work in menial jobs. Through rotation, people took part in every kind of work, but it interfered with any process of specialization.
