A strong learning culture means learning is a natural part of work, not something that happens at a course once a year. People ask, share, and try things out, and mistakes are used to get better.
Managers matter a lot for the learning culture. When the manager takes the courses themselves, talks about them, and gives time to use what was learned, employees follow.
Small, steady habits help. Short courses that fit into the workday and a regular follow-up at team meetings make it easier to keep the learning going.
