What leaves when a worker leaves
Experienced staff carry knowledge no manual captures. Keeping that wisdom in the organization may be one of the most valuable things a program can do.
Every organization has them: the staff member who knows exactly how to reconnect with a young person who's stopped showing up, or which words help a nervous job seeker walk into an interview. That knowledge took years to build. Most of it lives only in their heads.
When that person moves on, the knowledge usually goes with them. New staff start from scratch, often learning the same lessons the hard way.
Practice wisdom, in practitioners' own words
The most useful knowledge is rarely formal. It's the short story, the practical tip, the 'here's what worked for me.' Capturing it in practitioners' own voices — and connecting it to the research that explains why it works — makes it available to every new worker at the moment they need it.
Organizations that do this well don't reset with every new cohort of staff. Their knowledge compounds. And new workers feel less alone in a job that can be isolating.
