Cross-border staffing, done correctly.
Belgian and Dutch labour authorities inspect hard. We make sure every worker, every rotation, every document stands up to scrutiny.
EU Posting of Workers Directive
The Directive (96/71/EC, revised 2018/957) sets minimum working conditions for workers posted from one EU member state to another. Posted workers from Poland receive at least the host-country minimum wage, relevant sector collective agreements apply, and maximum working times are respected. Peritus manages this for every deployment.
Belgian Limosa declaration
Any worker arriving in Belgium for the first time must be declared via the Limosa system before their first day of work. Peritus files the declaration for every worker before travel begins. You receive a copy for your records.
A1 certificate of coverage
The A1 form confirms that a posted worker continues to pay social security contributions in Poland rather than Belgium. This prevents double-contribution situations. Peritus obtains the A1 for every worker before deployment.
Dimona / CLO registration
Belgian employers are required to notify ONSS of every worker's start and end date via Dimona. Where Peritus acts as the legal employer posting into Belgium, we handle this registration. We notify our client partners when this is relevant to their record-keeping.
Polish labour contract compliance
All workers employed by Peritus Sp. z o.o. hold a Polish labour contract under the Kodeks pracy (Labour Code). This protects worker rights, defines notice periods, holiday entitlement, and sick-pay obligations.
GDPR: candidate data
Peritus collects and processes candidate personal data for recruitment and placement purposes under Article 6(1)(b) of the GDPR. Data is stored in Poland, accessed only by authorised Peritus staff, not shared with third parties without consent, and deleted upon request.
How we audit sub-suppliers
When Peritus engages sub-contractors for specialist trades, we require documentary proof of labour law compliance: labour contracts, A1 certificates, and Limosa declarations. We do not pass compliance risk downstream.
This page describes our operating practice. It is not legal advice. For binding guidance on posting of workers, refer to your lawyer or the Belgian FPS Employment, Labour and Social Dialogue.
