The Independent reports:

The former employee said the device provided an order to collect from the warehouse and a set amount of time to complete it. If workers met that target, they were awarded a 100 per cent score, but that would rise to 200 per cent if they worked twice as quickly. The score would fall if they did not meet the target.

If, however, workers did not log a break when they went to the toilet, the score would be “surprisingly lower”, according to the former staff member, who did not want to be named but worked in an Irish branch of Tesco. He said that some would be called before management if they were not deemed to be working hard enough. “The guys who made the scores were sweating buckets and throwing stuff around the place,” he said. He said the devices put staff under huge pressure and many of his colleagues using them in Ireland were eastern Europeans, with limited English. He said lunch breaks did not result in staff being marked down. Tesco confirmed that the devices were also in use across its UK stores.

Tesco in Ireland told the Irish Independent that a “break” function could be used to register genuine stoppages and around 25 minutes had been allowed per day for that. But any other time would be monitored. A Tesco spokesman told The Independent: “Arm-mounted terminals are a working aid and at no time are they used to monitor colleagues while on their breaks. They make it easier for our colleagues to carry out their role as they don’t need to carry paperwork around the distribution centre.”
