I'm looking forward to this on tv tonight.
I worked there a few years back and whilst you can't really complain about paid employment in this day and age the conditions there are awful. I don't understand how the reporter managed to get a hidden camera in there as they have airport-style metal detectors for every member staff as they leave the shop floor.
The place is swelteringly hot and they do provide water stations but you need to drink loads which leads to a lot of toilet breaks. The toilets are tucked away in the corners and the place is so large (around 3/4 mile square) that a round trip (just the walking) is 7 or 8 minutes and this eats in to everyone's target times, which management will then hassle the staff about.
