Do you work with metal? Wood? No, I work with knowledge. I mine it, I process it, I chop it up into tiny pieces, I study it, I mix it with other ingredients, I put it back together, I mould it into new forms, I package it up, I send it and I get paid for what I make. 

We have Peter Drucker to thank the metaphor of the knowledge worker. Coined (another manufacturing metaphor) in the 1960s, it was a term he used to capture the essence of the work being done in corporate America. It was a time of shifting away from manual work to desk-based work with knowledge. 

Ever wondered why we talk about running a ‘workshop’ with other people? Or creating a toolkit of different approaches. It’s the knowledge worker metaphor.
