Section 28 asks for every working day to be written down on that day. Section 27 asks the operator to hold a valid registration (or alias) certificate and a valid health-counselling certificate before anybody works. So a worker goes on today's sheet only if, today, both are good and they have been told about both.
The name — or the alias on a valid alias certificate, in which case that certificate's validity and issuing authority go in its place. The health-counselling certificate's date and issuing authority. The day they were told about registration and counselling. Nothing else: no address, no date of birth, no photograph.
Every payment between a worker and the house, in either direction, with the name (or alias), the date and the amount. Daybook writes it down. It never takes, holds or sends a payment.
The date is today unless you change it. Anything entered after its own day is stamped late — written down honestly, never hidden.
What section 28 says must be shown on request: for each worker, the name or alias, the certificates, each working day, and every payment each way. Pick the days; print it or hand it over as a file.
The records are kept two years from the day each one was written, and then the personal data in them is deleted. Inside the two years nothing can be removed one line at a time — a ledger you can tidy is not a ledger. Past them, everything due goes in one press.
