According to an article in Transfert.net, Air France has been spying for years on some of its staff with the help of a camera hidden behind a clock. A union-member became suspicious when he took a close look at the thick electrical wires going to a clock in a private relaxation room on Roissy airport. Flipping the clock, he discovered a hidden camera. Asked for an explanation by the union CGT, Air France said the camera was only monitoring a door leading directly to a border, and would only be activated in case the door was opened. The camera was installed back in 1999, following orders from the airport security working-group.

The union wasn't satisfied with the answers, and wanted to know why the employees had not been properly informed about this camera. According to their statement, all other camera's on Roissy are marked with signs referring to the responsible authorities. Investigating the exact position of the camera, CGT concluded the view of the door was actually blocked by a clothing cabinet. Moreover, looking at the surveillance of a similar waiting-room, with a clearly visible camera outside, they couldn't understand why in this case Air France wanted to film the backs of possible intruders, instead of their faces.
