Fenner Fashions make high quality clothing. Unfortunately for Harold Fenner (Peter Jones), the shop steward, Paddy (played by Miriam Karlin), is on the look-out for any excuse to take the almost entirely female workforce out on strike. Consequently, every day is a battle between Paddy and Harold, aided (and often hindered) by the foreman, Reg (Reg Varney - changed to Tony, played by Christopher Beeny when the show went to LWT in 1977). But somehow they seem to pull together at the last minute and get things done.
