Dienst ist Dienst und Schnaps ist Schnaps — duty is duty and schnapps is schnapps. Two things, not to be mixed.
Nach Feierabend — after the working day, used as a time of day in its own right.
Urlaubsanspruch — holiday claim. Not an allowance or an entitlement in the soft sense. A claim, in the legal meaning, enforceable.
Abschalten — to switch off. What a German is expected to do at the end of the day, and the metaphor is electrical.
Betriebsferien. Many German companies close entirely for a fixed period, commonly in summer or between Christmas and New Year, with the works council agreeing the dates. Nobody is covering. Nobody is on call. The building is shut.
German shop opening hours were governed by federal law from 1956, and Sunday closing remains the rule across the country. Shops are shut. Not quiet — shut. A Sunday in a German town is a different kind of day, enforced by statute.
Celebration-evening. The German word for the end of the working day, and there is no English equivalent because English has no word for the thing.
Ich mache Feierabend — I am making Feierabend — is a complete sentence and a complete explanation. The day’s work is over, and what follows is not called leisure or free time. It is called a celebration.
Die Sonn- und Feiertagsruhe. Section 9 of the Working Hours Act prohibits work on Sundays and public holidays as a general rule, with exceptions for healthcare, transport, hospitality, emergency services and media. The protection of Sunday is not a workplace policy. It is a general prohibition with specific carve-outs, and the carve-outs have to be justified.
