The National Union of Hosiery and Knitwear Workers (NUHKW) was a trade union in the United Kingdom.
The union was founded in 1945, with the merger of five local unions: the Hinckley and District Hosiery Union, Ilkeston and District Hosiery Union, Leicester and Leicestershire Amalgamated Hosiery Union, Loughborough Federated Hosiery Union and Nottingham and District Hosiery Workers' Society. Shortly after, most Scottish unions voted to join the new organisation. Sections were also created for northern and southern England and, by the end of the year, it had 22,430 members. The following year, it secured a national agreement limiting night work and restricting total working to 45 hours per week.
In 1970, a threat of national strike action secured a 10% wage increase and the abandonment of plans for a continuous shift system. Membership of the union continued to grow, reaching a peak of 74,077 in 1977.
In 1969, the Nottingham Hosiery Finishers' Association amalgamated with the union, becoming its Nottingham (Finishers) District. This was followed by the Leicester and Leicestershire Trimmers' and Auxiliary Association in 1970, and then all the other minor unions in the industry. The long-established Amalgamated Society of Operative Lace Makers and Textile Workers also joined. However, widespread redundancies in the sector began reducing membership. In 1991, it merged with the National Union of Footwear, Leather and Allied Trades, with 34,183 members remaining to join the new National Union of Knitwear, Footwear and Apparel Trades.
