I am a good asset to this company.

Organisations run on knowledge that never got written down. Which supplier actually answers on a Friday. Which form comes back rejected if you fill in box nine. The knack for the machine that needs its handle lifted slightly before it turns.

None of that is in anyone's job description. It is why the week somebody is off sick can feel strangely difficult for reasons nobody can name.

Being useful and being visible are two separate systems, and they overlap less than they should.

You can usually tell which one you are by what stops when you are not there.
