In the spring of 1822 an employee in one of the world’s first offices – that of the East India Company in London – sat down to write a letter to a friend. If the man was excited to be working in a building that was revolutionary, or thrilled to be part of a novel institution which would transform the world in the centuries that followed, he showed little sign of it. “You don’t know how wearisome it is”, wrote Charles Lamb, “to breathe the air of four pent walls, without relief, day after day, all the golden hours of the day between ten and four.” His letter grew ever-less enthusiastic, as he wished for “a few years between the grave and the desk”. No matter, he concluded, “they are the same.” The world that Lamb wrote from is now long gone. The infamous East India Company collapsed in ignominy in the 1850s. Its most famous legacy, British colonial rule in India, disintegrated a century later. But his letter resonates today, because, while other empires have fallen, the empire of the office has triumphed over modern professional life.
