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 trade union 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 association 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.
