Sid Plummer is the site foreman bridging the gap between workers and management, shrewdly keeping the place going amid the unrest.

Vic's dim stooge Bernie Hulke provides bumbling assistance in both his union machinations and his attempts to woo Sid's daughter, factory canteen worker Myrtle.

Sid's wife is Beattie, a lazy housewife who does little but fuss over her pet budgie, Joey, which refuses to talk despite her intense efforts.

They fight their desires and ultimately decide not to have the tea, fearing that neighbours might see Sid enter Chloe's home and get the wrong idea.

At the picket lines the next day, Vic gets his comeuppance – partly at the hands of his mother, who spanks him in public – and the workers and management all pull together to produce the big order to save the firm.

The Monthly Film Bulletin wrote: "Twenty one Carry On... films have understandably exhausted the supply of lavatorial puns, and though the twenty-second does not scruple about re-using several of them, Talbot Rothwell tends generally to neglect his W.C. factory (a thinly disguised Pinewood Studios) for a series of irrelevant sketches ranging from farce (the works outing) to domestic comedy (Sid and the budgie).

The result seems even more scrappily assembled than usual and, with the exception of a fairly amusing parody of sex education films, the level of humour, though noticeably cleaner than of late, is still rock bottom.
