On the Buses (1971)

Stan gets a little annoyed when his mum and sister keep buying expensive items on hire-purchase, but the money he earns for overtime working as a bus driver means that he can afford it... just. His job is secure - bus drivers being hard to come by - and his overtime prospects are good, until the bus company decide to revoke a long-standing rule and employ female bus drivers. Aghast at the thought of no overtime - and, therefore, lower take-home pay - he joins forces with his long-time work colleague Jack to sabotage the new female employees.
