While many courses have finished for the summer there are Summer Schools working with Job Centre Plus students. Many of these students are from the EU and looking for work. Here is a useful link from the TUC Know Your Rights at Work document http://www.tuc.org.uk/tuc/working_in_the_uk.cfm
This may be a helpful resource for those of you here over the summer and working with JCP students.
You will find more useful information on all aspects of Rights at Work by following the link under Blogroll (right hand side of page).
