Carry On at Your Convenience is a 1971 British comedy film, the 22nd release in the series of 31 Carry On films (1958–1992), and was the first box office failure of the series. This failure has been attributed to the film's attempt at exploring the political themes of the trade union movement, crucially portraying the union activists as idle, pedantic buffoons which, apparently, alienated the traditional working-class audience of the series. The film, known as Carry On Round the Bend outside the United Kingdom, did not return full production costs until 1976 after several international and television sales. The film features regulars Sid James, Kenneth Williams, Charles Hawtrey, Joan Sims, Hattie Jacques and Bernard Bresslaw. It features Kenneth Cope in the first of his two Carry On appearances. The film was followed by Carry On Matron in 1972.

Plot

In bathroom ceramics factory W.C. Boggs & Son, the traditionalist owner W.C. Boggs (Kenneth Williams) is having no end of trouble. Bolshy and lazy union representative Vic Spanner (Kenneth Cope) continually stirs up trouble in the works, to the irritation of his co-workers and management. He calls a strike for almost any minor incident – or because he wants time off to attend a local football match. Sid Plummer (Sid James) is the site foreman bridging the gap between workers and management, shrewdly keeping the place going amid the unrest.
