Until January 2017, employers were not allowed to provide the SSN of their employees to third parties, unless the employees had given explicit permission. Subsequently, the implementation regulation was amended, whereby the lender or subcontractor is obliged to provide the SSN of the employed employees to the agency / contractor.
Before starting the work, the workers must identify themselves on the construction site. The SSN is checked against the SSN registered in De Bouwpas on the basis of the passport or the ID card of the worker. There is a legal basis for this, and you can not refuse this as an employee.
This SSN provision is necessary for the main contractor to be able to invoke the indemnity or mitigation of the hirer's and supply chain liability. The change ensures that the main contractor does not have to request the SSN from you as an employee, but can do this more efficiently from the agency or subcontractor, whereby the risk of errors is lower.
GDPR
But what about the GDPR? According to the GDPR, I don't have to share this? It is as follows: organizations outside the government may only use the social security number if this is provided for by law. In this case, there is a legal basis and obligation for the registration of the SSN.
It is of course important that the collected data is kept securely. At De Bouwpas we work hard to maintain this security every day.
