Why are we being watched more and more by technology, including in the workplace? Is it an aid to hard work, or prelude to oppression?

But to many, this technology has sinister potential. Professor Andre Spicer at Cass Business School in London says it is a reminder for employees of who is boss.

Ben Waber, president of a firm called Humanyze, tells presenter Ed Butler it has huge potential when it comes to spotting the previously unknown patterns of good productivity. Even having bigger lunch tables in the office canteen can increase output, as workers have more opportunity to chat and share ideas, he says.
