Question juridique clé
Whether the 4:00 a.m. shift change required a separate seco authorization under the Labor Act and Ordinance 2.
Solution extraite
No separate authorization was required; the shift pattern was compatible with the special rules for energy-supply undertakings.
Motifs extraits
For undertakings subject to special provisions, Art. 27 ArG allows deviations from the general working-time rules. Art. 10 ArGV 2 contemplates night work starting after 4:00 a.m., so such a schedule cannot be treated as unlawful per se. The special regime was meant to simplify administration, not to reintroduce a general approval requirement.
