Unfortunately others & myself have run into a rather dubious employer, who is blatantly avoiding certain obligations to the detriment of all.
Does anyone know where I can contact the French labour inspectors so they can be requested to take a closer look?
Thanks
Look up the Inspection du Travail for your local area. I am led to believe that they even have an anonymous call number for people to "dob-in" unscrupulous employers. Alternatively, your local branch of the URSSAF would almost certainly take an interest in this person if they were to be alerted of alleged illicit employment activities.
