After that she questions the relationship between law, collective agreements and individual agreement on remote control. Subsequently, she analyses the technological devices in use in the employment relationship, distinguishing between "control" and "work" tools and focusing on software. Furthermore, she reflect on the suitability of European privacy legislation for the protection of teleworkers against prejudices linked to the use of big data.
