> In 2018, a freedom of information request from the GMB union found that a Tesco warehouse in Rugeley, near Birmingham, recorded only eight ambulance callouts in three years versus the 115 logged at a nearby Amazon site. Both warehouses employed large numbers of workers at the time – 1,300 at Tesco’s site and around 1,800 at Amazon’s.
Not enough for me to get a conclusive picture. But sounds like it would make sense to take a deeper look.
