WLS works - quite excellently.

The education and training of our team, the open communication and management culture and the provision of appropriate and safe labour infrastructures play an important role for us. 
Numerous certifications highlight the importance of security to us. International corporations have audited us year after year according to strict criteria with very positive results.

In addition to these strict and highly demanding audits by our customers including unannounced, cross-country WLS internal audits, we also undergo external certification.
