The document discusses how lunchtime habits have changed in offices over the past few decades. Where workers once left their desks at 1pm to eat lunch together in the canteen, now many simply eat sandwiches at their desks while continuing to work through lunch. This erosion of the lunch break is problematic for worker well-being and productivity, as psychologists believe downtime is important. In fact, a campaign by BUPA called "Reclaim the lunch break" found companies could be losing £50 million per day in lost productivity from workers not taking breaks. Their research showed only 30% of staff now take a proper lunch hour, yet constant work without breaks may not be beneficial to health or productivity in the long run.
