For the employer
The employer keeps one household book: who works, which days count, the wage that was entered, the signed contract, and the permission to work. A payslip is drafted from those days. Pay under the statutory floor stays a draft, and so does a payslip when a required work permission is missing or out of date. Proof of payment is stored with the wage. The month and the year sit beside the household budget, with cleaner, nanny, garden, and maintenance kept apart.
