French to English Other Journalism Video clip for a documentary

There's a clip of a man working in a car factory, who's complaining about his job. He says that they're always talking about performance, imrpovement, going faster etc, but it's unrealistic. Then he says something that sounds like (the audio on the clip is poor, especially as there is a lot of background noise) 'chiodeur'. It does, however, seem to confuse the interviewer, who repeats the word to confirm it. The man then says 'c'est un métier de chiodeur' - any help decifering what this word could be would be much appreciated!
