From the Government of UK :
Workers have the right to one uninterrupted 20 minute rest break during their working day (this could be a tea or lunch break), if they work more than 6 hours a day.

I photographed employers during their lunch break in two of the major financial districts of the world, City of London and Canary Wharf.

The 400,000 or so people who work here, are employed in the fields of financial intermediation, accountancy, insurance and banking.
They face intense stress, they are in a constant state of preoccupation and strain and it doesn’t seem they can leave their job behind when they have their break.
I observe their routine and I catch their worried moods.
