Is Britain the most surveyed society in the world?

In today's Guardian an article 'Firms tag workers to improve efficiency ' says that: 'An increasing number of workers in warehouses across Britain are being "electronically tagged" by being asked to wear small computers to cut costs and increase the efficient delivery of goods and food to supermarkets. The system gives supermarkets access to the individual's computer so orders can be beamed from the store. The computer can instructs workers where to go to collect goods from shelves also check on whether they are taking unauthorised breaks and work out the shortest time a worker needs to complete a job.

Now trade unionists want safeguards to be introduced to protect privacy and academics are worried that the system could make Britain the most surveyed society in the world. The country already has the largest number of street security cameras.'
