Auf Wiedersehen Pet (1983)

Neville is suspended from work when his boss finds out that he's a bricklayer rather than a carpenter. Watching a group of men playing football, Neville spots an unexploded bomb which has been unearthed by a mechanical digger. He raises the alarm and is hailed as a hero. The boss finds a bricklaying job for him. There's a sudden vacancy because Oz has been in a fight with a group of Germans and has been sacked. The German workers go on strike until Oz is reinstated.
