The Labour Standards Register (The Register) is the public register of businesses that receives a positive outcome report based on NEN 4400-1 or NEN 4400-2 inspection performed by a inspection company such as Bureau Cicero. The Register can be consulted here.
In addition to The Register, there also is a List of Notified Companies (aangemelde ondernemingen). Companies that apply for a inspection and have enrolled on the website are included in this list. Registered businesses will appear only once in the Notified Companies list and for a maximum period of 3 months. By appearing on the List of Notified Companies, a company can show their customers that it's taking the proper steps to obtain an inspection certificate based on NEN 4400.
The NEN 4400 is applicable to all companies that perform work by commission or that provide manpower in The Netherlands. The inspection consists partly of a data check and partly a procedures check. Procedures can be recorded in writing, may have been entered in a computerised system or, in the case of smaller companies, may have been agreed verbally. The standard is therefore readily applicable also to smaller companies.
Within the NEN 4400 you have two standards: NEN 4400-1 & NEN 4400-2
NEN 4400-1 is a national standard that set requirements for temporary work businesses and contractors of work, including subcontractors. These companies have their registered office in the Netherlands with respect to:
The aim of the standard is to limit the risk of recovery and penalties for employers from the Dutch Tax and Customs Administration (and other government agencies).
NEN 4400-2 has been developed for companies that have their registered office outside the Netherlands. This standard includes requirements for checking and assessing any company having its registered office outside the Netherlands. And is a company that provides workers for the purpose of working under the supervision or direction of a third party. Also for testing and assessing any contractor or subcontractor having its registered office outside the Netherlands in order to determine that they are organised in such a way that it may be safely assumed that obligations from employment are complied with.
