Warehouse staff forced to wear armbands to monitor their workrate. It seems like a clear affront to human dignity to me.
Update, 15th February: I wrote to Tesco and got this response:
Thank you for your email. My name is Ann and I am a Customer Service Manager for Tesco.
The Tesco distribution centre at Donabate is a modern distribution facility employing modern work practices including the use of arm mounted terminals (AMT’s). AMT’s are a paperless order picking system used by our colleagues to help them with their daily workload. This has been common practice since the distribution centre opened and is a feature of working in any modern warehouse facility. AMT’s are a working aid and at no time are they used to monitor colleagues while on their breaks. A collective agreement is also in place with the SIPTU trade union.

That seems satisfactory enough, although the sentence "at no time are they used to monitor colleagues while on their breaks" seems a bit iffy to me. Are they used to monitor them during working time? And would executives and managers put up with that kind of monitoring?
All the same, I give them the benefit of the doubt.
