Hi
We work 2 mornings (07:00-14:00), 2 afternoons (14:00-22:00) and then 2 nights (22:00-07:00). The night shift is very quiet after about 23:00 and so normally 2 of the 3 night shift sleep for a number of hours so that they are reasonably fresh for 06:00, when the place goes beserk.
The daytime shifts should have at least 7 or 8 Heathrow controllers on duty although with the current shortage that isn't always possible. The law here requires a break after 2 hours although our agreement with local management reduces that to 1.5 hours. In reality it is more normal to work about 1 hour at a time.
On this Friday evening, the whole London operation, which is currently based near Heathrow will move to the main ATC centre near Southampton. This will then become the largest ATC centre in Europe.
