What are flash inspections?

Flash inspections are mainly designed to inform and prevent issues. The planned actions are announced in advance on the SIOD website. By providing this notice, every company has the chance to ensure compliance. Sanctions will only be imposed in cases of serious or repeated violations.

What does the inspection look for?

In addition to moonlighting (RSZ declaration) and illegal employment (single permit, work cards and permits), the social inspection also checks other social obligations in your company:

Labour regulations
Including all work schedules and mandatory annexes, such as the annex on psychosocial risks.
Labour contracts and annexes
For example, labour contracts for part-time work, student work, flexi-jobs, or temporary work.
Control cards of unemployed workers
Dimona declaration
Occupational accident insurance
Registration of deviations from work schedules
If applicable: documentation or registration system for deviations for part-time workers (more/less hours or varying work schedules compared to the planned fixed or variable work schedule).

The inspection also checks compliance with specific obligations in your sector, such as:

The proof of work declaration (AVW) and Checkin@work (C@W)
The proof of basic safety training (or equivalent through experience or other training)

Frequently asked questions

Is a flash inspection 'less strict'?

Not necessarily. Flash inspections are announced, preventive inspections with an informative purpose. However, inspectors can still write a report and impose sanctions for serious or repeated violations. Therefore, ensure that your company is compliant.

Can inspectors come unexpectedly?

Yes. Flash inspections are announced at the sector level, not for individual companies. Inspectors have broad powers to enter workplaces without prior consent. However, they need authorization or permission to access private areas. An unannounced visit to your company is therefore possible.

What if something is missing?

For minor shortcomings, you will usually first receive a warning and a deadline to comply. Serious or repeated violations can lead more quickly to a report and possible sanctions. Prevention is better than cure.

How do I prepare my team for flash inspections?

Make sure everyone knows who will speak to the inspectors, where the necessary documents are located, and what needs to be shown. Keep identification documents, labour contracts, and employment documents readily available. A short briefing beforehand can help reduce stress.

What are the possible sanctions?

The Social Penal Code provides for administrative fines, criminal fines, and even imprisonment. The severity of the fine or the imposition of a prison sentence depends on the level of the violation.

Example

In the construction sector, since 1 April 20214, electronic attendance registration on construction sites, namely Checkin@work, has been in effect. The obligation for attendance registration applies to everyone performing work on immovable property at a workplace whose total cost is equal to or greater than 500,000 euros (excluding VAT).

If a violation is established, committed by the employer, appointee, or agent, it is punished with a level 3 sanction.

This involves either an administrative fine between 800 euros and 8,000 euros, or a criminal fine between 1,600 euros and 16,000 euros. A criminal fine can only be imposed if the labour auditor decides to initiate proceedings in court.

The judge may also impose an additional sanction, namely an operating or professional ban or a business closure.

Additionally, any person who enters a temporary or mobile construction site and does not immediately and daily register their presence on the construction site is punished with a level 1 sanction. A level 1 sanction can only be an administrative fine, the amount of which varies between 80 euros and 800 euros.
