My role was to label data according to strict guidelines. It was expected that we labelled 6 hours a day with the highest concentration possible, because while every detail mattered, it also had to be as fast as possible (everything was tracked by the minute).

Any doctor or sports performance specialist will tell you that processing data 6 hours everyday with high levels of concentration and speed is extremely stressful for the human brain and quickly ends in burnout.

But our work was tracked and measured as if we were machines, not humans.
