What are flash inspections?
Flash inspections are mainly designed to inform and prevent. The planned actions are announced in advance on the SIOD website. By announcing these actions beforehand, every company has the chance to be compliant. Sanctions are only applied in cases of serious or repeated violations.

What does the inspection look at?
Besides moonlighting (NSSO declaration) and illegal employment (single permit, work cards and permits), the social inspection also checks other social obligations within your company:
- Work 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 agency work. - Control cards of unemployed workers
- Dimona declaration
- Industrial accident insurance
- Registration of deviations from work schedules
If applicable: documentation or registration system for deviations in part-time workers (more/less hours or varying work schedules compared to the fixed or variable work schedule provided).
The inspection also checks compliance with specific obligations in your sector, such as:
- The specific Dimona declaration and the number of days of employment for occasional workers (extras)
- The registration of the performances of a flexi-job worker (possibly via the Registered Cash Register System)
Frequently asked questions
Is a flash inspection ‘less strict’?
Not necessarily. Flash inspections are announced, preventive inspections with an informative purpose. However, inspectors can draw up a report and impose sanctions in cases of serious or repeated violations. So make sure your company is compliant.
Can inspectors come unexpectedly?
Yes. Flash inspections are announced at sector level, not for individual companies. Inspectors have broad powers to enter workplaces without prior permission. For private premises, however, authorisation or permission is required. An unannounced visit to your company is therefore perfectly possible.
What if something is missing?
For minor shortcomings, you usually first receive a warning and a period to become compliant. Serious or repeated infringements lead more quickly to a report and possible sanctions. Prevention is better than cure.
How do I prepare my team for the flash inspections?
Make sure everyone knows who will speak to the inspectors, where the necessary documents are kept, and what needs to be shown. Keep identity documents, labour contracts and employment documents within reach. A short briefing beforehand can avoid a lot of 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 imprisonment depends on the level of the infringement.
Example
In the hospitality sector, flexi-job workers may be employed. The performances of these flexi-jobbers must be registered and kept up to date.
An employer who employs flexi-job workers without registering and keeping track of the correct start and end times of the work performance through a system is punished with a level 3 sanction.
A level 3 sanction is either an administrative fine of 1,000 euros to 10,000 euros, or a criminal fine of 2,000 euros to 20,000 euros.
