in 1977, the ruling parties of zanzibar and mainland tanzania, the tanu and the asp merged to form chama cha mapinduzi (ccm). likewise, the tanu-affiliated union, the only labor organization in the country, was restructured. the union of tanzanian workers or jumuiya ya wafanyakazi tanzania (juwata) was thus founded in the following year. it continued the nuta's tradition of complete loyalty to the ruling party, but covered all of tanzania, including zanzibar, although the government of the region was reluctant to allow unionist activity to resume on the island.
