In order to ensure synchronized operation of companies who use workforce around the world, work schedules have been divided in two or three shifts and a large number of people work in evening or night shifts. Based on interviews with 25 employees of a call centre in Romania, I describe three processes: sleep desynchronization, i.e. working during night and sleeping during the day, synchronization with those having similar nocturnal schedules and, finally, its resynchronization with the mainstream. I describe the tensions and conflicts which accompany each such transformation.
