Swiss work culture, in three words
Punctual, precise, direct. The rest follows.
Punctual: five minutes early is on time. On time is late. If you are running late, message the meeting before the clock strikes, not after.
Precise: numbers, dates, and commitments are kept as stated. Vague enthusiasm reads as unreliable.
Direct: Swiss colleagues will tell you exactly what they think, quietly, without softening it. Do not read that as rude. Return the favour.
The upside: contracts are honoured, roles are respected, and you rarely work weekends unless something has actually broken.
