Clements Kadalie was born in April 1896 in Nkhata Bay District at Chifira village near the Bandawe mission station in Nyasaland, presently Malawi. He was the second born son of Mr. and Mistress Musa Kadalie Muwamba.
He was the grandson of Chiweyu, a paramount chief of the Tonga of Nyasaland.
After a short stint of primary school teaching, Kadalie joined the stream of Nyasalanders seeking employment in neighboring South Africa in early 1915. In 1918, Kadalie settled in Cape Town. Here he befriended Arthur F. Batty, an emerging trade unionist and political activist.
In early 1919, with Batty"s advice, Kadalie founded the Industrial and Commercial Union (Intensive Care Unit), later renamed the Industrial and Commercial Workers" Union of Africa, to protest against unfair labour laws and to protect workers" rights.
The Intensive Care Unit spread in the mid-twenties throughout South Africa until 1927, when it could boast a membership of one hundred thousand—the largest trade union ever to have taken root in the continent of Africa. Kadalie headed the Intensive Care Unit from its inception in 1919 until his resignation as national secretary in 1929.
In December 1919, Kadalie gained prominence with the success of the dockworkers" strike, which prevented the export of all goods through Cape Town Harbour facilities. The dockworkers" strike lasted fourteen days and involved 2,000 mentor
The strike laid the foundation for Kadalie"s development into a leader known to thousands of people within South Africa.
On 24 November 1924, Kadalie was arrested and issued with a deportation order, naming him a prohibited immigrant and ordering him to leave South Africa within three days. In May 1927, Kadalie represented the Intensive Care Unit at the international Labour Conference in Geneva. In 1928, internal fighting within the Intensive Care Unit saw Kadalie being sacked by William G. Ballinger with the full backing of the executive committee of the Intensive Care Unit. In May 1928, Kadalie and six other trade union leaders of the union were arrested under the Native Administration Acting.
The Acting made it a criminal offence to arouse racial animosity towards the white population.
Kadalie later formed an independent Intensive Care Unit in East London. Kadalie died in 1951.
Kadalie"s granddaughter, Rhoda Kadalie, is a prominent academic, columnist and Executive Director of the Impumelelo Social Innovations Centre.
On top of that, Kadalie was a provincial organiser of the African National Congress (African National Congress).
