Are You Being Served? - Season 3 Episode 2 -

Captain Peacock complains when he notices the staff are taking leisurely coffee breaks. After his complaint is reported, management(Mr.Rumbold) orders for a time keeping book in which the staff will "clock in and clock out" whenever they go to coffee, lunch or the washroom. With heavy protest, the staff organize a union, and refuse to acquiesce to managements orders until their demands are met.
