The PAWW (Private Supplement WW and WGA) is a benefit to supplement the austerity on the WW or WGA benefit. The benefit will expire after a maximum of 2 years and the PAWW scheme ensures that you keep financial security for longer, up to a possible 14 months extra benefit.
This scheme applies to you as temporary worker, since the Collective Labor Agreement (cao) for temporary workers has made agreements about this with the PAWW Foundation.
You must request the supplement yourself. More information can be found on the website of the PAWW Foundation: www.spaww.nl.
